Power distribution characteristics of millimeter wave dielectric waveguide loaded with a thin slab of solid-state plasma

摘要

Seventy GHz millimeter wave power distribution in dielectric waveguide loaded with a thin slab of solid-state plasma material has been investigated theoretically by means of FDTD method. The results elucidate that the cross-sectional power distribution is greatly varied by the magnetic field applied perpendicularly to the plasma slab. Experimental results show qualitative agreements with the theoretical ones. The possibility of constructing a Y-type circulator and other non-reciprocal devices is demonstrated. Operation in sub-millimeter wave frequency range is also suggested.
