Enhanced higher order MoM-PO modeling using multiple reflections in the PO region

This paper proposes a higher order MoM-PO technique with enhanced accuracy in the PO region based on a multiple-bounce improvement of the solution for PO currents. According to this new technique, the solution for PO current coefficients is computed as the initial solution obtained from the MoM current coefficients within the MoM-PO interaction process plus the contribution from multiple bounces within the PO region using PO-PO interactions only, in a number of iterative steps. The hybrid solution is further improved by nesting a PO-PO multiple reflection procedure within every iteration in an overall iterative process covering the entire MoM-PO computational domain, with multiple reflections between MoM and PO currents.
