Abstract
The magnetic field dependence of 526 GHz submillimeter-wave propagation in two-layer waveguides containing p-type InSb slabs was studied in detail whi le varying the ambient temperature, and the results were compared with theo retical predictions. It was shown that, at the liquid nitrogen temperature, the submillimeter-wave propagation loss is very small, typically 0.3 dB/mm , and that fabrication of a submillimeter-wave image guide employing a p-In Sb slab may be possible. At the dry ice temperature, slow surface wave reso nance was clearly observed and a nonreciprocity of at least 15 dB was obtai ned with an insertion loss of 5 dB. These results indicate that the constru ction of nonreciprocal devices in submillimeter-wave monolithic integrated circuits may be possible. It is also suggested that this nonreciprocal wave propagation can be controlled by injecting plasma in the InSb slab.
