Departmental Bulletin Paper 金属円盤型THz表面波分割器のFDTD解析におけるパワー評価

楠, 大輝

Terahertz (THz) surface wave splitters based on spoof surface plasmon polaritons (SPP) in metal grating structures are analyzed using the finite-difference time-domain (FDTD) method.We investigate a three-dimentional disc-type splitter at separate frequencies of 1.0 and 1.5 THz.The power propagating in each direction is evaluated using the Poynting vector.Key Words : Finite-difference time-domain (FDTD) method, Spoof surface plasmon polaritons(spoof SPP), Terahertz (THz) wave, frequency splitter
