Spin Must Be Added to the Moment of Poynting Vector

Authors: Radi I. Khrapko
Comments: recovered from sciprint.org

Calculating of absorption of a circularly polarized light beam and an analysis of the celebrated Beth's optics experiment show that the standard electrodynamics needs a concept of classical spin for completing. The spin is presented.

Professor Soper's Mistake

Authors: Radi I. Khrapko
Comments: recovered from sciprint.org

The impossibility to obtain the electrodynamics Maxwell tensor in the framework of the Lagrange formalism is confirmed by a professor Soper's mistake made on this way. Nevertheless, a heuristic method allows using the Lagrange energy-momentum and spin tensors for obtaining the classical spin tensor.

A Rotating Electric Dipole Radiates Spin and Orbital Angular Momentum

Authors: R. I. Khrapko
Comments: recovered from sciprint.org

According to the standard electrodynamics, a rotating electric dipole emits angular momentum mainly into the equatorial part of space situated near the plane of the rotation where polarization of the radiation is almost linear. Polar regions situated near the axis of rotating are scanty by the angular momentum, although they are intensively illuminated by the almost circularly polarized radiation, which must carries spin angular momentum. A conclusion is made that the electrodynamics sights orbital angular momentum only and overlooks spin. This means that the electrodynamics is not complete. We introduce a spin tensor into the electrodynamics and calculate the whole angular momentum flux radiated by the dipole.

Moment of the Poynting Vector is not Spin. V. 2

Authors: R. I. Khrapko
Comments: recovered from sciprint.org

A common opinion that a moment of the Poynting vector is spin is a common delusion due to a serious defect of the general field theory. We present a circularly polarized Laguerre-Gaussian beam without an azimuth phase structure as an evidence of this. It is shown that the moment of the Poynting vector in this beam is an orbital angular momentum, not spin. Meanwhile, this beam, as well as a circularly polarized plane wave, clearly carries spin. But the standard electrodynamics does not sight it. Spin tensor of the standard electrodynamics is zero. So, this delusion causes many conflicts, vagueness, and paradoxes concerning electromagnetic angular momentum. The only way to resolve the problems is to use an electrodynamics spin tensor, which we introduced into the electrodynamics and demonstrate in this paper.

Where is the Polarization Energy Hidden and Where Does the Force Act?

Authors: R. I. Khrapko
Comments: recovered from sciprint.org

It is shown that the quadratic dependence of electric energy on electric strength causes an additional electric energy in comparison with the energy corresponding to a macroscopic electric field. The force acting on a dielectric, in general, does not act on the bound polarization charge. The Maxwell stress tensor in dielectric is considered.

Paradox of the Classical Beth Optics Experiment

Authors: R. I. Khrapko
Comments: recovered from sciprint.org

A celebrated Beth's experiment contradicts the angular momentum conservation law in the frame of Maxwell electrodynamics because Beth's birefringent plate experienced a torque without an angular momentum flux in the surrounding space. However, this paradox can be removed by introducing a classical spin tensor.

Does Volume Force, or Does Surface Force Act on Polarized Dielectric?

Authors: Radi I. Khrapko
Comments: recovered from sciprint.org

Static electric field in linear uniform neutral dielectric is divergence-free and irrotational. Thus the Maxwell stress tensor is divergence-free as well. So, according to Maxwell, the volume force is ZERO. Only surface forces act on the polarized dielectric.

Field Tubes and Bisurfaces in the Electromagnetism

Authors: Radi I. Khrapko
Comments: recovered from sciprint.org

Faraday's field lines are not enough for an adequate graphical representation of electromagnetic fields, It is necessary to use bisurfaces, The bisurfaces and field tubes replacing the field lines permit to represent evidently for example how electric current creates magnetic field and electric field produces scalar potential field, A conception of differential forms and contravariant tensor densities is used, We say that an exterior derivative of the form or a divergence of the density result in boundaries of the geometric quantities, The integration of the quantity by the Biot-Savarat formula results in a new quantity, We name the quantity a generation, Generating from a generation yields zero, So generations are sterile as well as boundaries are closed. A conjugation is considered The conjugation converts a closed quantity to a sterile quantity and back, The conjugation differs from the Hodge operation, The conjugation does not imply a dualization, Chains of field and an analog of Hodge decomposition theorem are considered

Electrodynamics' Spin

Authors: R. Khrapko
Comments: recovered from sciprint.org

We solve the angular momentum problems of the electrodynamics. We show that a desire of using a spin density proved to be correct for evaluating of the electrodynamics spin because the moment of momentum is an orbital angular momentum density and does not encompass the spin. However, the expression is not a true expression for the spin density. This expression yields correct results in simplest cases randomly. Its improvement is hopeless. Instead we present a true spin density of electromagnetic waves and demonstrate a way for its deducing. Our result can be expressed by a sum of the orbital and spin angular momentums.

Authors: R. Khrapko
Comments: recovered from sciprint.org

The canonical spin tensor of the standard electrodynamics is inadequate. This is shown by the use of a plane electromagnetic wave and a standing electromagnetic wave as examples. An improvement of the tensor by adding of a magnetic term is considered. The true spin tensor is demonstrated.

Calculation of Absorbed Spin Contradicts Electrodynamics and an Experiment

Authors: Radi I. Khrapko
Comments: recovered from sciprint.org

Absorption of a circularly polarized light beam without an azimuth phase structure in a dielectric is calculated in the frame of the standard electrodynamics. We calculate a transfer of energy, momentum, and angular momentum to the dielectric. The calculation shows that the force acting on the dielectric does not have a surface term and the angular momentum flux in the beam equals to two power of the beam divided by frequency. This results contradict an experiment of A. Bishop et al. (PRL, 92, 198104), a paper of R. Loudon (PRA, 68, 013806), and another part of standard electrodynamics, which predicts the flux equals to power of the beam divided by frequency. At the same time the last part of the electrodynamics contradicts to the classical Beth's experiment (PR, 50, 115). To correct this part of the standard electrodynamics we introduce a spin tensor. The corrected electrodynamics is in accordance with our calculation and with the Beth's experiment. But we cannot help the Bishop's and Loudon's results.

The Beth Experiment is Under Review

Authors: R. I. Khrapko
Comments: recovered from sciprint.org

It is shown that the modern Maxwell electrodynamics cannot explain the result of the Beth experiment. So, the modern electrodynamics is not complete. A spin tensor is used for an explanation of the experiment. It is shown that this tensor completes the Maxwell electrodynamics. A theory of the Beth's experiment is presented.

Absorption of a Circularly Polarized Beam in a Dielectric, Etc.

Authors: Radi I. Khrapko
Comments: recovered from sciprint.org

We calculate absorption of a circularly polarized light beam without an azimuth phase structure in a dielectric in the frame of the standard electrodynamics. A transfer of energy, momentum, and angular momentum from the beam to the dielectric is calculated. The calculation shows, in particular, that the angular momentum flux in the beam equals to two power of the beam divided by frequency. This result contradicts another part of the electrodynamics, which predicts the flux equals to power of the beam divided by frequency. In addition we show that this part of the electrodynamics contradicts the classical Beth's experiment. Our inference is: the electrodynamics is incomplete. To correct the electrodynamics, we introduce a spin tensor into the electrodynamics. The corrected electrodynamics is in accordance with our calculation and with the Beth's experiment.

Inevitability of the Electrodynamics' Spin Tensor

Authors: Radi I. Khrapko
Comments: recovered from sciprint.org

Theoretical reasons and results of the works: Phys. Rev. A68 013806 (2003), Opt. Lett. 22 52 (1997), Optics Express 14 6963 (2006), Phys. Rev. Lett. 92 198104 (2004), Phys. Rev. Lett. 91 093602 (2003), Phys. Rev. Lett. 88 053601 (2002) prove that the angular momentum flux carried by a circularly polarized light beam with plane phase front equals two power of the beam divided by the frequency. This fact contradicts the standard electrodynamics, which predicts the beam's angular momentum flux equals power of the beam divided by frequency, and means the electrodynamics is incomplete. To correct the electrodynamics, a spin tensor is used.
