Calculation of Transmission Coefficient of Bismuth Planar Waveguide in Magnetic Field in the Far Infrared Range

EasyChair Preprint 9478

Abstract

The paper aims to study the behavior of a system consisting of a planar waveguide made of bismuth and located in a magnetic field. The electromagnetic wave is propagating through a waveguide whose walls are made from anisotropic monocrystal. Passage through the planar waveguide of a laser radiation leads to cyclotron absorption of electromagnetic radiation. The quality of a crystals and value of k_BT=0.36 meV permit to observe cyclotron resonances and dielectric anomalies of electrons and holes in L and T points of the Brillouin zone. A convenient physical model and a mathematical model are provided where a classical point of view is considered by the use of Maxwell’s equations to model the propagation of electromagnetic wave. Newton’s method was used to solve the characteristic equations in complex plane. The complete algorithm for calculation of the shapeline of the magnetooptical experiment in far infrared range of spectrum is submitted.

Keyphrases: Transmittance, anisotropic monocrystal, infrared radiation, planar waveguide
