Abstract
An electromagnetic sensor for use in a variety of applications requiring extremely high sensitivity, such as measuring power and characteristics of incident electromagnetic radiation includes a superconducting layer that carries an exchange field for providing a spin splitting effect of charge carriers in the superconducting layer, a metal electrode, and an insulating layer arranged between the superconducting layer and metal electrode to form a spin filter junction therebetween. The electromagnetic sensor provides an antenna including a wave collecting element, in contact with the superconducting layer to convey thereinto external electromagnetic waves that are generated by an external source. An electric measurement device provides an output signal responsive to the amplitude and frequency of the external electromagnetic waves, and contacts the metal electrode to measure an electric current or voltage caused by the spin splitted charge carrier flow from the superconducting layer through the spin filter junction into the metal electrode.
