Abstract

The electromagnetic radiation due to flux flow from type II superconductors has been investigated. The effect of small non-laminar flux motion is simulated, and the radiation power is calculated and analyzed. The calculations show that for a little non-laminar effect, the harmonic frequencies do not change, but the power will be changed proportional to this effect. Therefore, the system will radiate at the harmonics of the famous washboard frequency with a widening of its frequency. Considering this unwanted effect is necessary for optimization and modeling of flux flow based devices, especially THz devices. The behavior of the obtained power is similar to the experimental results.
