Abstract :
This paper is devoted to the experimental investigation of a new class of superconducting microwave oscillators based on Cherenkov radiation from Josephson vortices. Samples consisting of a long Josephson junction embedded in a dispersive transmission line with space-periodical inhomogeneities were fabricated and tested. We report observation of new resonances on the I-V curve of the system and present the first radiation measurements in the 80-120 GHz frequency range.
