Equivalent Circuits Application of Pin-Diodes and MEMS-Keys in Electrodynamic Modeling Problems

This article studies the possibility of using circuit formats to describe radio components in electrodynamic modeling problems. The study was carried out on example a controlled metamaterial form an electromagnetic crystal with SPICE-models equivalent circuits pin-diodes and MEMS-keys. Also, Touchstone files as alternative format for describing radio-electronic considered. obtained results are illustrated by scatter matrix plots, well SPICE code. Obtained can be used design structures that combine active nonlinear microwave devices.
