  • Abstract
    A general finite-element method is applied to compute the skin current of a perfectly conducting surface illuminated by an incident electromagnetic wave. Surface charges over any element and currents flowing through any edge are approximated by polynomials of degree m. Some radiation patterns of two horns are calculated and compared with those obtained from experiment.
