Analysis of the numerical error for time domain MEI absorbing boundary condition

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.
