Construction of algorithms based on the impedance grid method for the electrodynamic analysis of two-dimensional structures with arbitrarily distributed permittivity and permeability

A new technique is proposed for constructing algorithms for the time-domain electrodynamic analysis of two-dimensional structures with arbitrarily distributed permittivity and permeability. Five modifications of the algorithm are presented for different fillings of the domain under study. The algorithms obtained are compared in the required memory space and the number of arithmetic real-number operations.
