Computation and measurement of microwave metallic photonic crystal point-defect-cavity

Abstract

By changing the radius of the rod in the center of a point-defect-cavity (PDC) based on metallic photonic crystals (M-PhCs), a novel type of microwave cavity with an adjustable resonant-frequency is proposed and studied. After the illustration of the band structure of M-PhCs, the first 3 resonant modes of the point-defect-cavity (PDC) are computed by supper… (More)
