Abstract :
The frequency characteristics of Josephson own radiation have been studied by means of Fourier spectroscopy. The FIR measurements were performed with the help of Fourier spectrometer coupled with the Nb Josephson junction. The main feature of this technique is that one Josephson junction operates as both generator and detector of own radiation at the same time. The spectrometer operates either in double-beam mode with resolution /spl sim/2 GHz or in multi-beam mode with resolution /spl sim/1 GHz.<>
