PHYSICAL INTERPRETATION OF THE TRANSPARENT ABSORBING BOUNDARY FOR THETRUNCATION OF THE COMPUTATIONAL DOMAIN

Physical interpretation of the recently introduced transparent absorbi ng boundary for the grid termination in finite methods shows that the absorbing domain in that method is described by the constitutive equat ions of moving media. The field solutions in this domain give the requ irements for the material parameters to provide zero reflection at arb itrary incidence angles and arbitrary polarizations of the incident wa ves.
