Abstract :
This paper presents an efficient method of moments solution of the mixed potential integral equation formulation for a general microstrip structure in a multilayer medium. The spectral domain Green´s functions for multilayer media are derived and the spatial domain Green´s functions in the form of Sommerfeld integrals are then evaluated by the discrete complex image method. The asymptotic waveform evaluation is applied to efficiently evaluate the frequency response over a band of interest. Numerical results have demonstrated the efficiency and accuracy of this method.
