Birefringence and Dichroizm of Porous Aluminum Oxide Filled with Titanium Dioxide

Abstract

Birefringence and dichroizm of a porous aluminum oxide layer filled with titanium dioxide is calculated for the model of an effective medium. Oblique incidence of ordinary and extraordinary waves is considered. A dependence of the layer transmittance on the angle of electromagnetic wave incidence is compared with the available experimental data. The sensitivity of the experimental technique suggested previously to the change of the refractive index of the pore filler is investigated.
