Abstract
The measured equation on invariance is applied in time domain (TDMEI) to find the absorbing boundary conditions. The TM radiation of a line source at 1/4 computational domain in a 2-D free space is used as a test example to examine how good the TDMEI is in comparison with conventional absorbing boundary conditions (ABC), such at Mur´s (1981) 2nd order ABC and perfectly matched layer (PML), etc. It is found that the TDMEI is more accurate than both ABC and PML for the radiation problem.
