Abstract :
A scheme for detecting millimeter- and submillimeter-wave radiation by utilizing a paramagnetic material is described. An analysis of the scheme, which indicates the dependence of the noise-equivalent power on various parameters is given. Experimental results obtained at 35 and 50 GHz are presented. The scheme can be extended to higher frequencies by choosing the proper material and coupling structure.
