Abstract

In this paper, the influence of two different time approximation techniques on the accuracy of the finite difference time domain (FDTD) method has been analysed. The following approximation techniques have been considered: time-average (TA) and exponential time differencing (ETD). Both algorithms have been implemented in an own developed FDTD simulation environment. In particular, an example of an on-body antenna on the human tissue is considered, as a possible case of interest.
