Abstract :
In this paper we introduce a universal Method of Moment (MoM)-based formulation, which overcomes some of the drawbacks of conventional frequency domain techniques. Formulating the problem in a way that bypasses the evaluation of the electric field as a summation of scalar and vector potential terms enables us to overcome the low-frequency breakdown when applied to the solution of the Surface Electric Field Integral Equation (S-EFIE). The direct evaluation of the electric fields reduces the impedance matrix fill time compared to the conventional MoM. The Equivalent Medium Approach (EMA) can be applied in conjunction with the proposed formulation for the solution of microstrip circuits embedded in stratified environments.
