Simulation results for a novel optically-controlled photonic bandgap structure for microstrip lines

A novel optically controlled one dimensional (1D) photonic bandgap (PBG) microstrip structure is proposed. This device consists of a 50 /spl Omega/ microstrip transmission line and a PBG ground plane both deposited onto a photoconductive substrate. With no optical illumination the structure exhibits...
