Abstract
A scheme for increasing the frozen-mode bandwidth of a nonreciprocal magnetic photonic crystal (MPC) has been introduced. Finite-element methods in both the frequency and time domains are used to numerically investigate the dispersion characteristics of both chirped and nonchirped MPC structures. Chirping was observed to increase the bandwidth of the MPC at the expense of lower frozen-mode amplitude. Two applications of chirped MPCs have been suggested: an isolator and delay line
