摘要：

A novel concept of the normal metal hot-electron microbolometer with capacitive coupling of an absorber to the antenna (NHEB-CC) is proposed. Tunnel junctions can be used for high-frequency capacitive coupling giving perfect isolation of hot electrons in the small volume of the absorber. This concept represents a further development of the basic idea of an antenna-coupled bolometer, used in the realization of normal-metal hot-electron microbolometers with Andreev mirrors (NHEB-A). The NHEB-CC technology with capacitive isolation of the absorber avoids the likely problems of frequency limitation for frequencies with an energy quantum h omega higher than the superconducting gap Delta and brings other advantages in comparison with NHEB-A system.
