Abstract :
This paper highlights a fast and accurate full-wave modal integral technique based on the calculation of inner products obtained through the Galerkin´s procedure, when trial functions taken in the account the edge effects are used. By using trapezoidal numerical integration with nonuniform discretization steps, the proposed approach allows fast calculation of such inner products, thus significantly reducing the required CPU-time for microstrip-type structure analysis. The efficiency of the proposed technique is demonstrated through a successful comparison of the dispersion characteristics to published data.
