Abstract :
Absorbing boundary condition (ABC) formulations are derived for low loss media from lossy one way wave equations. The results of a numerical study are presented showing that errors in a low loss computational domain, due to the reflections from the domain boundaries, are significantly lower when the boundaries are terminated by these ABCs instead of those derived for lossless media
