An alternative version of the time-domain electric field integral equation for arbitrarily shaped conducting structures is presented. The advantage of the present approach is that the electric field integral equation has one less derivative with respect to time than the popularly used one. Hence, with this approach one does not need to differentiate the excitation. Therefore impulse and step function excitations of the conducting structures are possible in addition to the conventionally used Gaussian excitations. This alternative version is also quite accurate compared with a frequency-domain solution.
