✦ Synopsis

Figure Reflection coefficient as a function of the frequency and the resolution interpolation conductivity was chosen in order to obtain a normal theoretical reflection coefficient of 0.001% s y100 dB. Results for the reflection coefficient as a function of frequency are presented in Figure .

6. Conclusions

In this paper, a general method for the construction of EPML absorbing boundary conditions has been developed. The general matching conditions for three-dimensional electric and magnetic anisotropic media have been found. A simple continuity hypothesis of the fields at the boundary has enabled us to enclose the general theory under simple algebraic conditions. The method has been validated in the time domain through the use of the FDTD method, although the conditions obtained here are also suitable for other frequency-and time-domain methods.
