Analysis of Propagation Eigenmode for Stripline based on Planar Circuit Equations and Lateral Equivalent Network

Stripline/microstrip line is an important waveguide component for MIC. Theoretical treatment of propagation eigenmode for stripline/microstrip line of infinitesimally thin strip has been established. However, theory for thick strip line is not yet established. In order to treat propagation eigenmode of stripline/ microstrip line with thick strip, rigorous equivalent network in the lateral direction is derived based on mode analysis and planar circuit theory. Derived equivalent network is practically applied to the analysis of propagation eigenmode for stripline of any thickness with succes
