Spatial evolution of cylindrical beams in complex media

Abstract

The spatial evolution of vector electromagnetic fields in bianisotropic cylindrically symmetric structures is studied. We introduce evolution operators (characteristic matrices), impedance tensors, reflection and transmission operators of cylindrical beams which are convenient for describing waves in layered media. We predict the existence of fractional Bessel beams with integer topological charge and cylindrically symmetric beams which can be presented as the product of the Bessel function and the exponent. We investigate energy and polarization characteristics of such beams.
