Abstract: The possibility of using the Josephson heterostructure composed of a nanoscale metallic absorber separated from superconducting strips by thin insulating layers as a high-sensitivity microwave detector has been considered theoretically. The inductive response of such a detector has been calculated and the influence of the nonequilibrium of the electron subsystem of the metallic absorber on its response has been analyzed. The limiting sensitivity of the proposed detector has been found.
