“…The transcendental linear dispersion equation system of the 8th order determinant for open circular cylindrical semiconductor waveguides with external dielectric layer is expressed by D s = det[a jk ] = 0, where j is a column and k is a row index of determinant. The non-zero complex determinant elements are presented in [13]. Solving the dispersion equation, the phase characteristics of the modes and other electrodynamics parameters are obtained.…”

This paper focuses on the analysis technique of gyrotropic circular cylindrical semiconductor waveguide by the use of an electrodynamical model. Authors propose the semi-automatic extraction of the dispersion characteristics by the use of single-layer perceptron neural network. The waveguide analysis algorithm consists of four main stages: initialization of system parameters, evaluation of transcendental linear dispersion equation system, extraction of dispersion characteristics and evaluation of the waveguide broad bandwidth. In this paper three types of waveguides (n-InP, n-InSb and p-InP) are analysed using a proposed algorithm. According to the results of analysis, the use of gyrotropic n-InP and p-InP semiconductor, semiconductor-dielectric waveguides are more preferred than to n-InSb waveguides due to their wider broad bandwidth.

The aim of this paper was to introduce the estimation of the losses in the prototypes of the microwave devices. We proposed in this paper two algorithms: an algorithm for evaluation of losses in the microwave devices based on a waveguide and an algorithm for evaluation of losses in the microwave devices based on a meander line. In order to verify the results of losses evaluation for the waveguide-based device, we have used the electrodynamic model of the open cylindrical gyrotropic waveguide with one anisotropic dielectric layer and the electrodynamic model of the open cylindrical gyrotropic waveguide with two dielectric layers. In order to verify the results of losses evaluation for the meander line-based device, we have used the model of the meander line with asymmetrical periodical inhomogeneity. The comparison of the losses evaluation results received by the algorithms proposed in this paper and the results received by application of the commercial software together with the alternative methods confirmed that the proposed algorithms produced correct results.
