PML and MUR 'ABC' time-domain analysis in PSTD algorithm

The pseudospectral time-domain (PSTD) method is a new way for solving Maxwell's equation. It's based on the FFT (fast Fourier transform), since it utilizes the PWS expansion to represent the spatial derivatives. Meanwhile, the periodicity of the FFT produces so called "wraparound effects"-a major limitation of its application. The article shows the feasibility of this algorithm by numerical examples, and presents two methods (PML and MUR ABC) for overcoming the problem, giving a comparison of both methods in one dimension.
