NOVELTY - Detector of terahertz emission of bolometric type includes Josephson junction on the basis of thin-film structure containing layers of superconducting material, between which there arranged is absorber from normal metal, which is connected to source of measured signal. Layers of superconducting material are parallel connected to offset current source and measuring circuit inductively connected to magnetic field sensor on the basis of squid and recording geometry. Absorber from normal metal has the shape of elongated strip and is arranged through layers of dielectric between layers of superconducting material; at that, the above strip is connected to the source of the measured signal by means of the elements connected through layers of insulator to its edges with possibility of providing mutually perpendicular directions of flow of supercurrent and the measured signal. USE - Electricity. ADVANTAGE - Increasing response of the detector to microwave emission, reducing the noise factor, possibility of implementing four-point probe measurement circuit, as well as integration with squid information readout devices.
