Abstract
A novel technique is presented for the determination of the optimum conductivity profiles of the PML and PML-D. A closed-form interpolation function of numerical reflection coefficients with respect to the frequency and the conductivity profiles is given by extending the multiple-variables pade approximation. With the closed-form expression, the anneal simulation optimum algorithm is used to minimize the reflection coefficient of PML and PML-D for a given frequency range. Numerical experiments are presented to show that a significant performance improvement can be achieved by optimizing the conductivity profiles of the PML and PML-D.
