摘要

In 3 the P1 developed a scaling argument that proved useful in the derivation of reflectionless sponge layers to absorb outgoing time-harmonic waves in numerical solutions of the three-dimensional elliptic Maxwell equations in rectangular, cylindrical, and spherical coordinates. Also, this work developed these reflectionless sponge layers to absorb outgoing transient waves in numerical solutions of the time-domain Maxwell equations and proved that these absorbing layers are described by causal, strongly well-posed hyperbolic systems. A representative result was given for wave scattering by a compact obstacle to demonstrate the many orders of magnitude improvement offered by the developed approach over standard techniques for computational domain truncation.
