Application of space domain integral equation technique for high frequency description of open microstrip discontinuities

The full-wave electrodynamical analysis of the open microwave discontinuities is performed by the space domain integral equation approach. This approach employs the dyadic Green's functions for a grounded multi-layer dielectric configuration and can be used on a single or multi-layer dielectric with or without superstrate. The method of moments is used for numerical solving the received equation. Elements of respective impedance matrix are calculated by combination of analytical and numerical integration. The characteristic network parameters of structure are determined on the know matrix elements.
