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.

  1. Merely wanna input that you have a very nice website , I love the style and design it really stands out.

  2. But a smiling visitor here to share the love (:, btw great design. “Treat the other man’s faith gently it is all he has to believe with.” by Athenus.
