Analysis of the power handling capability of a superconducting stripline structure using complex images

摘要

Power handling capability of a HTS strip depends on the maximum current density at its corners. In this paper, an efficient and numerically stable method was discussed to compute the current distribution over the cross section of a superconducting strip in a stripline structure. The problem is formulated in terms of a set of coupled integral equations for the interior and exterior regions. The method of moments was then used to solve the equations. An accurate fast convergent Green's function was used in the method for the exterior region. The exterior integral equation was also used to extend the output data of the moment method to approximate the current density very close to the comer.
