Abstract:

This report discusses an approach to characterizing complex media, based on the use of new families of orthonormal electromagnetic beams. Each family consists of orthonormal exact solutions of Maxwells equations, which differ fundamentally from the well-known approximate solutions - the Hermite-Gaussian and Laguerre-Gaussian beams. A promising type of such orthonormal beams-beams defined by the spherical harmonics-is discussed. The proposed approach makes it possible to use beams focused into a small spot on the sample surface.
