Investigation of Anisotropic Cylindrical Semiconductor-Dielectric Waveguides

Abstract

The use of semiconductor-dielectric waveguides is low at the moment due to disadvantage of high attenuation of electromagnetic microwaves. The attenuation depends on structures and materials of semiconductor-dielectric waveguides. Dependences of transmission coefficient on the frequency of semiconductor-dielectric waveguides and on different densities of electrons in semiconductors are studied in this paper. As well as the influence of periodicity on transmission of electromagnetic microwaves in semiconductordielectric waveguides is discussed. It is shown that frequency dependences of transmission coefficient of periodical semiconductor-dielectric waveguides obtain the properties of the band pass filter. Also it is shown that the choice of semiconductor and dielectric materials have a significant impact on the nature of the transmission and attenuation of electromagnetic microwaves.
