✦ Synopsis

Perfectly matched layer PML absorbers deteriorate the condition of the resulting finite-element sparse systems. Therefore, poor con¨ergence scenarios are obser¨ed when an iterati¨e sol¨er is employed. In this work, we show that, by choosing the PML parameters in an optimal manner, substantial speedup in the solution con¨ergence is achie¨ed without affecting PML absorption. A robust preconditioned sol¨er with nearly no breakdown possibilities is suggested, implemented, and tested for two microwa¨e circuit applications.

Perfectly matched anisotropic absorbers are introduced in two-and three-dimensional beam propagation methods. The anisotropic perfectly matched layer does not require the modification of Maxwell's equations, and can be easily implemented in codes which deal with anisotropic materials. Finite-element
