We present experimental and numerical results for a flux flow oscillator based on superconducting Josephson junctions. Our computationally efficient theoretical model takes into account Josephson self-coupling of the flux flow oscillator and is in a good agreement with our experimental results and previous studies.
Keywords: flux flow oscillator, superconducting Josephson junctions, fluxons, Terahertz radiation.
