Практичні аспекти застосування матричної електродинаміки в моделюванні НВЧ-приладів

Abstract

Some practical aspects of the matrix electrodynamics application to solving the computational problems in electronics are considered. The main specificity of the new method consists in the treatment of electrodynamic systems (ESs) of microwave electron devices as oscillatory systems with a finite number of the degrees of freedom. ES is considered as a lattice of spatially localized partial oscillators (oscillets). The eigenfrequencies and eigenfunctions of the ES can be calculated basing on the matrix theory of oscillatory systems with lumped elements. The advantage of this approach is substitution of the partial derivative differential equations with the linear algebra problems
