An experimental double-layer active frequency-selective surface(AFSS) for stealth radome is proposed. The AFSS is a planar structure which is composed of a fixed frequency-selective surface(FSS), a PIN diodes arra...
我们对氮化铌(NbN)热电子测热辐射计(Hot Electron Bolometer,简称:HEB)的太赫兹(Terahertz,简称:THz)混频器的稳定性进行了研究,并探讨了相应的简易稳定方法.我们测量了HEB THz混频器在4.2K温度下使用0.65THz本振源(Local Oscillator,...
