Time-domain EM numerical modelling

Abstract

A number of model-pulses to be used for feeding purposes in time-domain, electromagnetic simulations are compared. The pulses' causality and temporal support are employed as discriminating features. CST Microwave Studio® simulations of a canonical configuration are employed for assessing the pulses' suitability. In view of their entailing numerical accuracy and short temporal signatures, the time-differentiated windowed-power (∂tWP) and the time-differentiated power-exponential (∂tPE) are shown to represent opportune alternatives to the standard CST Microwave Studio® (Gaussian) pulse for performing simulations.
