【Abstract】 A finite difference method was derived for the analysis of time domain electric field integral equation(TDEFIE) of thin wire structures. This method is easier to numerate implementation than the traditional time domain method of moment. Three classical electromagnetic radiation/scattering cases of thin wires were considered for comparison. The results confirmed that the finite difference scheme is very efficient for the solution of TDEFIE of thin wire.更多还原
