摘要：Using the finite difference time domain method, the electromagnetic field distribution of terahertz waves are simulated in photonic band gap structures with different single-defect, line-shaped defects and L-type defects composed of three single-defects. Introducing the photonic band gap structure with difference coordinates single-defects, the resonance frequency and amplitude of the single-defect along the vertical direction of line-shaped defects waveguide have more sensitive than the parallel direction. Introducing the photonic band gap structure with line-shaped defects composed of three defects, the resonant in the endpoint of line-shaped defects have high amplitude and in the middle of line-shaped defects have two resonant frequencies. Introducing the photonic band gap structure with L-type defects composed of three defects, three high-Q resonant frequencies appeared simultaneously in the some monitor coordinates.
