Abstract:

The magnetic field dependence of 526 GHz and 671 GHz submillimeter-wave propagation in waveguides containing InSb slab was studied in detail varying the ambient temperature. It was shown that, at the liquid nitrogen temperature, submillimeter-wave propagation loss is very small, typically 0.3 dBmm, and that a submillimeter-wave image guide employing p-InSb slab may be possible. At the dry ice temperature, slow surface wave resonance clearly appeared, and a nonreciprocity of at least 15dB was obtained with an insertion loss of 5 dB. The possibility of constructing electrically controllable nonreciprocal devices in submillimeter-wave monolithic integrated circuits is presented.
