영문 초록

In this paper, we present a stable computation of the transient near-field scattered from the conducting objects. We solve the time-domain integral equation by expressing the transient behavior of the induced current in terms of weighted Laguerre polynomials. By using tms basis functions for the temporal variation, the time derivative in the integral equation can be handled analytically. Since these temporal basis functions converge to zero as time progresses, the transient response of the induced current does not have a late time oscillation. To show the validity of the proposed method, we solve a time-domain combined fiela integral equation and compare the results with the inverse discrete Fourier transform (IDFT) of the solution obtained in the frequency domain.
