Abstract

The Tera hertz radiation from a finite size superconductor media inside a magnetic field has been investigated. The tera hertz radiation is due to the flux flow motion inside the media. The electromagnetic fields inside the superconductor due to fluxons are calculated and using those fields, the radiation is obtained. In this research, the effects of finite size on the radiated power and signal mean width are investigated. The results show that by increasing the superconductor thickness, the peak values of harmonics increase and the mean width decreases.
