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