Such FFO made with the use of flux cloning circuit can in principle operate even without magnetic field, that is in a very different manner than conventional FFO [1] developed nowadays for practical applications [2, 3]. We have designed such a novel device and build it up with the use of the long Josephson T-shaped junction of a linear overlap geometry made up with Nb-AlO x -Nb technology. We have theoretically described the properties of such a device and the dynamics of vortices there. These theoretical studies have been performed in the framework of a sine-Gordon model, which includes surface losses. Finally we have tested the device experimentally and demonstrated that the flux cloning can lead to a strong coherent terahertz radiation. There the shape of the spectral lines and the current-voltage characteristics have been also measured.  ISSN : 1874-6500  Journal Name : NATO Science for Peace and Security Series B: Physics and Biophysics  Volume : 2011  Issue Number : 1  Publishing Year : 1432 AH 2011 AD  Article Type : Article  Added Date : Tuesday, June 12, 2012  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email هناء فرحان حسن Farhan-Hassan, Hanaa Researcher Doctorate hfarhan@kau.edu.sa D R Gulevich Gulevich, D R Researcher Doctorate   P N Dmitriev Dmitriev, P N Researcher Doctorate   V P Koshelets Koshelets, V P Researcher   valery@hitech.cplire.ru F V Kusmartsev Kusmartsev, F V Researcher Doctorate F.Kusmartsev@lboro.ac.uk Files File Name Type Description  33579.pdf pdf Abstract Back To Researches Page
