Outline of Final Research Achievements

The main results of a study are summarized as follows.
By application of the global bandgap of metallic photonic crystal (M-PhC) structure, novel monopole-mode resonators were proposed to design bandpass filters in microwave and millimeter-wave bands. In order to compute the photonic bandgap of the metallic photonic crystal, we carried out the numerical implementation of the plane wave expansion method and also performed the FDTD (finite-difference time-domain) numerical simulations. The bandgap structure of the proposed square-lattice M-PhC is calculated as well as the mode chart of the monopole-mode point-defect resonator. Through this study, we showed that M-PhCs are effective for applications to electromagnetic wave circuits such as waveguides, resonators, power dividers and switches, etc. even in the microwave /millimeter wave band.
