RegisterQuasi-static analysis, full-wave analysisQuasi-static analysis of a microstrip transmission line consists in modeling a dominant mode (mode quasi-TEM) propagating along the line, by a transversal electromagnetic wave. Field distribution of such wave can be determined by a static analysis of the structure (microstrip is assumed to be of the potential 1 Volt, the shielding waveguide is grounded). Quasi-static analysis gives good results typically below 5 GHz. If a microstrip transmission line is going to be analyzed on higher microwave frequencies, then full-wave methods have to be applied, which are based on a direct solution of Maxwell equations. Back
