    • A multilayered radiation detector device (50) including a resonant cavity structure wherein one cavity wall electrode includes a portion of a photovoltaic radiation detector (52). Specifically, a RFM detector has a superconducting transmission line electrode (54) electrically coupled to a high mobility semiconductor layer (58) of the photovoltaic detector. The superconductor transmission line electrode inductance forms, in combinations with a photodetector depletion region capacitance, a series resonant or a parallel resonant circuit. A radiation-induced change in the capacitance results in a change in the circuit resonant frequency and a corresponding variation in the amplitude of an on-resonance RF signal applied to the circuit. In another embodiment the resonant cavity structure includes a gap having a width that is modulated by an amount of absorbed radiation, the radiation-induced change in the distributed cavity capacitance resulting in a change in the cavity resonant frequency.
    • 一种包括谐振腔结构的多层辐射检测器件(50),其中一个腔壁电极包括光伏辐射探测器(52)的一部分。 具体地,RFM检测器具有电耦合到光电检测器的高迁移率半导体层(58)的超导传输线电极(54)。 超导体传输线电极电感与光电探测器耗尽区电容组合形成串联谐振或并联谐振电路。 辐射诱发的电容变化导致电路谐振频率的变化和施加到电路的共振RF信号的幅度的相应变化。 在另一个实施例中,谐振腔结构包括具有被吸收辐射量调制的宽度的间隙,分布式空腔电容中辐射引起的变化导致腔谐振频率的变化。
