Abstract:	In this paper, the electromagnetic (EM) characteristics of a transparent source for the finite-difference time-domain (FDTD) method are reported. The full wave characteristics are investigated via the convolution technique. The impulse response of the E field is decomposed into the quasi static term and the radiated term via the excitation of the delta function. On the other hand, the decomposition of the impulse response of the H field is achieved via the excitation of two unit step functions instead. In addition, the concepts are extended to all the FDTD grids such that, through the proposed technique, we are able to animate the radiated (not the total) EM field in the near zone of the transparent source for the FDTD method.
