Abstract(in Japanese) (See Japanese page)
Abstract(in English) Finite Differential Time Domain (FDTD) analyses were applied on 500GHz range submillimeter wave propagation characteristics in a Y-junction containing n-type InSb slabs as solid-plasma materials. By the appropriate selection of the parameters such as the geometries of the waveguide and of the plasma materials, the angle of the Y-junction and the magnitude of the applied magnetic field, a difference of 22.4 dB appears between the transmissions of the two different branches of the junction. The insertion loss of the branch with the larger transmission is calculated to be about 1.4 dB. Reverse of the direction of the applied magnetic field changes the roles of the two output ports. These results implies the possibility of applying the structure to non-reciprocal devices such as circulators.
