Abstract

Abstract

A new symmetrical formulation without O(1/R2) singularity is presented to cal-culate the impedance matrix elements as long as the rooftop basis functions have the character of local continuity. With this new formulation, one needs only take care about the O(1/R) singularity that is very easy to resolve. Several different types of rooftop basis functions are analyzed and compared, on which our formulation is applied. Numerical results are presented which have proved the validity, the efnciency and the universality of the new formulation.
