Abstract

The power deflection characteristics of 526 GHz submillimeter waves in a waveguide loaded with a thin n-InSb slab as a solid-state plasma material have been theoretically analyzed by the finite-difference time-domain (FDTD) method and experimentally measured at liquid-nitrogen temperature. It was shown both theoretically and experimentally that, by applying an external magnetic field B perpendicular to the solid-state plasma slab, a displacement takes place in the power distribution of the transmitted waves. These results indicate the possibility of using our waveguide in circulators of submillimeter-wave frequency range.
