摘要：

The optical control of a microstrip one dimensional (1-D) photonic bandgap (PBG) structure has been demonstrated over the frequency range 7-13GHz. A microstrip PBG structure. was fabricated on Duroid 6010 and a high resistivity photoconductive. Si wafer was placed in, contact with the ground plane. With no optical illumination incident upon the Si, the microstrip PBG filtering properties are well-defined. When the Si is illuminated the filtering properties arc suppressed. Under illumination the experimental results display an increase in S-21 of 6.5dB and a reduction in S-11 of more than 8dB at the centre frequency of 10GHz. Experimental results are presented alongside those simulated.
