Abstract

A frequency dependent Whytney-element time-domain (WETD) method is proposed for the calculation of the interaction between transient electromagnetic fields and frequency dependent materials. The proposed formulation is efficient since recursive convolution techniques are applied for the time domain implementation of the dispersive material characteristic. The method is suitable for the computation of the transient response in biological tissues, water and plasmas excited by pulse electromagnetic sources
