Field distribution in a waveguide loaded with a thin plate of n-InSb

Microwave field distributions were measured when a thin plate of n-InSb was placed vertically at the center of a K-band waveguide, and also when the waveguide was filled with n-InSb. The field distributions were asymmetrically deformed in the applied magnetic fields, and the propagation properties were demonstrated to be nonreciprocal.
