ON THE CONSTRUCTION AND ANALYSIS OF ABSORBING LAYERS IN CEM

A recently introduced system of partial differential equations, based on physical considerations, which describes the behavior of electro-ma gnetic waves in artificial absorbing layers, is analyzed. Analytic sol utions are found, for the cases of semi-infinite layers and finite dep th layers, both for primitive and characteristic boundary conditions. A different set of equations that seem to offer some advantages is pro posed in this paper. The properties of its solutions for the same geom etries and boundary condition are also discussed, (C) 1998 Elsevier Sc ience B.V. and IMACS. All rights reserved.
