Popis:	SUMMARY The temperature and magnetic field dependence of 526-GHz submillimeter wave propagation characteristics in surface waveguide utilizing an n-InSb slab as plasma material have been studied experimentally and theoretically. The results of theoretical analysis indicate that a surface wave resonance occurs and nonreciprocity of more than 27 dB/mm appears in the transmission in an applied magnetic field of 0.2 T at 77 K, and that at temperatures above 180 K, increases with increasing temperature. Experimentally observed results are in qualitative agreement with theoretical predictions. These findings indicate the possibility of achieving nonreciprocal devices in a surface waveguide consisting of an n-InSb slab.
