Abstract
- In this paper, we propose a uniaxial perfectly matched layer (PML) method for solving the tilne-harnlonic scattering problems ill two-layered media. The exterior region of the scatterer is divided into two half spaces by all infinite plane, on two sides of which the wave number takes different vahms. We surround the conlputational donmin where the scattering field is interested by a PML with the uniaxial medium property. By imposing homogeneous boundary condition on the outer boundary of the PML, we show that the solution of the PML problem converges exponentially to the solution of the original scattering problem in the computational dolnain as either the PML absorbing coefficient or the thickness of the PML tends to infinity.
