Abstract

Here we present the rigorous electrodynamical solution of microwave scattering by a multilayered electrically or (and) magnetically anisotropic circular cylinder. The number and thickness of layers may be arbitrary. We present the solution when all area of multilayered cylinder can be made of different uniaxial anisotropic or isotropic materials. The multilayered cylinder media can be of strongly lossy materials. The signs of the complex permittivity and permeability tensor components can be positive or negative in different combinations. Here we present the numerical dependencies of the Poynting vector radial component P_ρ that is responsible for the scattered and absorbed powers when the incident microwave impinges on the anisotropic Lithium Niobate (LiNbO₃) cylinder as well as on two single isotropic cylinders. The permittivity tensor components of the anisotropic cylinder are ε_t=43-i0.0005, ε_p=28-i0005 as well as for the isotropic cylinders the permittivities are ε_t=ε_p=43-i0.0005 and ε_t=ε_p=28-i0.0005. We show here the pattern of the value P_ρ inside and outside of the LiNbO₃ and two isotropic cylinders when the polar angle changes from 0 to 360 degrees with the step equal to one degree. We present here our calculations when the incident microwave has perpendicular or parallel polarization at three frequencies 65 GHz, 92.5 GHz and 120 GHz. We found that the values P_ρ for the anisotropic cylinder have the opposite behavior of dependencies on the permittivity tensor components for the incident microwaves of different polarizations.
