Analysis of a Time-Space Periodic Filter Structure with Tunable Band-Pass Characteristic
Abstract:
A periodically in time and space modulated medium gives rise to an electromagnetic bandgap structure. The band characteristic can be shifted by tuning of the time modulation of the medium. We compare the effect of a sinusoidally modulated structure on the bandgap using an FDTD implementation for curved moving boundaries with an approximation to the analytic solution derived from Floquet’s theorem. For the latter one we consider the mutual coupling of a finite set of time-space harmonics.
