Analysis of a two‐octave polarization rotator using the method of equivalent boundary conditions

摘要

AbstractA rapid analysis of a two‐octave, 45° polarization rotator is achieved by the approximate method of equivalent boundary conditions (EBC). Results achieved by this approximation and the conjugate gradient‐FFT (CG‐FFT) appear to be closely matched, with differences well within measurement error. Computation speed is significantly improved when compared with purely numerical techniques. © 1994 John WileySo
