Abstract

A direct three dimensional finite difference time domain (FDTD) method is applied to the analysis of a flash plate dipole (FTD) sensor used for transient field measurements. The sensor response to a double exponential transient wave and a Gaussian pulse are obtained and analysed. The capacitance and the equivalent area of the sensor are obtained and their variations with the structural dimension of the sensor are determined and compared with that obtained by the conventional method.
