Abstract

The measured equation of invariance (MEI) method is applied widely in the numerical simulation of the EM scattering problems. The paper discussed the reflection errors of time domain MEI-ABC, and compared with other truncating boundary conditions. The results shown that, by applying the time domain MEI-ABC, the accuracy of the MEI-ABC is higher than other methods for the case of truncating boundary near to the source. It is proved that the time domain MEI-ABC is an effective method of high accuracy and is less time consuming to treat the problems of EM radiation.
