Abstract :
An efficient finite-element approach for the eigenmode analysis of unbounded guided-wave problems is described using decay-type infinite elements. To determine an optimum set of decay parameters, two algorithms based on successive approximation are presented and their validity is checked by application to an optical fiber problem
