摘要

The temperature and magnetic field dependences of 671 GHz submillimeter-wave propagation characteristics in a transversely magnetized image guide consisting of a p-InSb slab have been studied experimentally and theoretically. The result of the theoretical analysis indicates that the propagation loss of this image guide is as small as about 0.116 dB/mm at liquid-nitrogen temperature. As the sample temperature increases to 240 K, a surface wave resonance occurs and a nonreciprocity of more than 20 dB appears in the transmission in an applied magnetic field B of 0.45 T. Experimentally observed results are in good quantitative agreement with theoretical predictions. These findings indicate the possibility of fabricating nonreciprocal devices embedded in a submillimeter-wave image guide consisting of a p-InSb slab. It is also shown that the attenuation of and nonreciprocity in the wave propagation in this image guide can be controlled by injecting plasma into the p-InSb slab.
