Abstract
This letter reports on the acceleration of the infinite series summation in the multilayered shielded microstrip with multiple strips by using the spectral domain immitance approach (SDIA) and the Levin's transformation. This technique does not need the asymptotic expansion for the Green's functions and the basis functions by recasting the matrix elements into the form that is evaluated by the Levin's transformation. It greatly saves the work for finding the asymptotic expansion coefficients. Using only the first leading term extraction, the overall acceleration performance is further improved. Convergence properties of SDIA by using this method match with or are even better than other acceleration techniques with high order leading term extraction.Keywords
