Abstract :
A new method for determining the equivalent single-layer relative permittivity of a multilayer microstrip structure, based on a quasistatic analysis, is reported. The method is based on superimposing the charge density distribution of the multilayer structure on the single-layer equivalent structure. This then enables the frequency-dependent effective permittivity of the multilayer structure to be evaluated using the Getsinger dispersion model
