Rotation of Linear Polarization Plane and Circular
, 802
"... Abstract. We show that a time evolving pseudo-scalar field coupled to the electromagnetic tensor generates circular polarization and does not only rotate the plane of linear polarization. We compute analytically and numerically the propagation of the Stokes parameters from the last scattering surfac ..."

Natural Lighting of Vegetation based on Polar Planes
"... We present a lighting method for outdoor scenes with vegetation. The method is compatible with multiresolution trees generated using random L-systems. We include a sky dome model that gets the luminance and chromaticity values at several sampling points for different time and location. The samples a ..."

are used to compute the light arriving to the objects in the scene depending on the insolation conditions. The method proposed is based on the form factor and polar plane concepts. These concepts are used not only to illuminate leaves or ground, but to solve visibility problem too.
Optical Flow Computation in the Log-Polar Plane
- in Proc. Int. Conf. on computer analysis of images and patterns CAIP
, 1995
"... : Vision systems with spatially homogeneous resolution are not able to provide a real time response in a dynamically changing environment. A reactive behavior necessitates selective sensing in space. Such a selection can be accomplished by the combination of a space-variant resolution scheme and a ..."

. The most convincing model is the theory of logarithmic polar mapping. In this paper we propose two new methods for the estimation of the optical flow and its spatial derivatives in the log-polar plane. We study analytically and experimentally the effects of the polar deformation and the decimation due
Analysis and Design of Waveguide Iris Polarizer for Rotation of Polarization Plane
"... Abstract In this paper, the simplified design methodology for rotation of polarization plane using a square waveguide is proposed. In order to optimize the characteristics of ∘polarizer operating from 14.3GHz to 14.8GHz in Ku-band, the modified mode matching method and piecewise power tower interpol ..."

Circularly polarized plane waves in a deformed Hadamard material
, 2001
"... Small-amplitude inhomogeneous plane waves propagating in any direction in a homogeneously deformed Hadamard material are considered. Conditions for circular polarization are established. The analysis relies on the use of complex vectors (or bivectors) to describe the slowness and the polarization of ..."

TIME-VIOLATING ROTATION OF THE ELECTROMAGNETIC WAVE POLARIZATION PLANE BY A DIFFRACTION GRATING
, 1997
"... The equations describing the T-violating photon scattering by a diffraction grating have been obtained. It is shown, that the T-violating rotation of the photon polarization plane appear under diffraction in a noncenter symmetrical diffraction grating. The rotation angle gives rise sharply, when the ..."

Attentive visual motion processing: computations in the log-polar plane
- Accepted in "Computing, Archives for Informatic and Numerical Computation
, 1995
"... Attentive vision is characterized by selective sensing in space and time as well as selective processing with respect to a speci c task. Selection in space involves the splitting of the visual eld in a high resolution area- the fovea- and a space-variant resolution area-the periphery. Both in neurob ..."

in neurobiology and in robot vision, models of the resolution decrease towards the image boundaries have been established. The most convincing model is the theory of log-polar mapping where very high data compression rates are achieved. In combination with the complexity reduction we believe that the log-polar
ABSTRACT Study of the Form Factor Calculation by Single Polar Plane
"... The Polar plan method for the calculation of the form factor is an alternative to the existing projective discrete methods (hemicube, tetrahedron, cartesian infinite plane, etc). This method is classified within the methods based on Nusselt’s analogy by infinite plane like Sillion’s and Puech’s. The ..."

Inhomogeneous “Longitudinal ” Circularly- Polarized Plane Waves in Anisotropic Elastic Crystals
"... Conditions on the elastic stiffnesses of anisotropic crystals are derived such that circularly polarized longitudinal inhomogeneous plane waves with an isotropic slowness bivector may propagate for any given direction of the normal to the sagittal plane. Once this direction is chosen, then the wave ..."

PHENOMENON OF THE TIME-REVERSAL-VIOLATING PHOTON POLARIZATION PLANE ROTATION BY A GAS PLACED TO AN ELECTRIC FIELD
, 1998
"... many years ago [1], and remains one of the great unsolved problems in elementary particle physics. Since the discovery of the CP-violation in decay of K0-mesons, a few attempts have been undertaken to observe this phenomenon experimentally in different processes. However, that experiments have not b ..."

According to [6] the violation of the time reversal symmetry stipulates the appearance of the new optical phenomenon: the photon polarization plane rotation and circular dichroism in an optical homogeneous isotropic matter placed to an electric field. This T-odd phenomenon is the kinematic
