| Abstract: | A finite element method has been used to research the electromagnetic response characteristic of HTS. A 2D finite element model is given, based on the H-Formulation. Through validating with a strip geometry, there is a good agreement between the result of model and that of theory. The AC response and electromagnetic force of HST with different geometries have been analyzed. It is shown that the model could reflect the correct electromagnetic behavior of HTS and could be extended easily. |
