THE COMPETITION OF BRAGG REFLECTION AND FRESNEL'S REFLECTION OF ELECTROMAGNETIC WAVES IN THE ARTIFICIAL HELICOIDAL BIANISOTROPIC MEDIA WITH LOCAL CHIRALITY

摘要

On the base of the exact solution of the boundary-value problem for artificial helicoidal media with local chirality we describe the reflection of electromagnetic waves on the periodic structure of medium as well as Fresnel's reflection from sample's boundaries. It allows to model the transmission and reflection of electromagnetic waves in dependence on the obtained parameters of artificial helicoidal medium and to design the device for polarization transformation. A possibility of the minimizing of size of a structure for transformations of the polarization state of electromagnetic waves is shown.
