Temasek laboratories efficient full-wave EMC (TLEFEMC V 1.0) code for analysis of antennas mounted on large and complex platform: Introduction, validation, and application

Fast and accurate full-wave analysis of antennas mounted on large and complex platform is very useful and yet a challenging area in electromagnetic compatibility (EMC) assessment. This paper introduces our Temasek Laboratories (TL) efficient full-wave EMC (TLEFEMC V1.0) code for attempting to solve this challenging problem up to a certain frequency of interest. This code is a great effort made by a team in TL at National University of Singapore (TL@NUS) in collaboration with DSO National Laboratories. The technical core of the TLEFEMC V1.0 code is the combination of surface-wire integral equation (SWIE) and precorrected-FFT (P-FFT) algorithm. Extensively numerical validation for small problems as well as applications to realistic targets has illustrated the capability of the developed code.
