摘要：
Perfectly matched layer (PML) absorbers deteriorate the condition of the resulting finite-element sparse systems. Therefore, poor convergence scenarios are observed when an iterative solver is employed. In this work. we show that, by choosing the PML parameters in an optimal manner, substantial speedup in the solution convergence is achieved without affecting PML absorption. A robust preconditioned solver with nearly no breakdown possibilities is suggested, implemented, and tested for two microwave circuit applications. (C) 1999 John Wiley & Sons, Inc.
