Outline of Final Research Achievements

Terahertz-technology in recent years has the potential to develop new capabilities for imaging, short-range and secured communications, remote sensors, spectroscopy, and material analyses etc. In order to realize the THz indispensable functional devices such as filters,various THz waveguiding structures have been proposed and some typical structures have a parallel plate metal waveguide, NRD (H-guide), and substrate-integrated waveguide (SIW), etc. This report proposed a new dual-mode bandpass filter using higher-order de-generate resonant modes of a square lattice photonic crystal microcavity in the terahertz frequency band. In order to design a photonic crystal high-Q microcavity, the dispersion relations of photonic bandgap are calculated by using the plane wave expansion method. The transmission properties of proposed dual mode filters for THz applications are numerically investigated.
