WebThe polarization of freely propagating light is always perpendicular to the direction in which the light is travelling. The dipoles that produce the transmitted (refracted) light oscillate in the polarization direction of that … WebIn optics, it is a standard way of estimating diffraction effects. In radio , this approximation is used to estimate some effects that resemble optical effects. It models several interference, diffraction and polarization effects but not the dependence of diffraction on polarization.

"WebThus, this optic will transmit the polarization component perpendicular to the structures alignment direction. This type of polarizer is therefore a polarization filter, as only one component is transmitted and the other is absorbed. Since this optic functions by absorption, it is only useful for low powers, typically in the mW range. " - Optics polarization
