POWER HANDLING CAPABILITY OF A HTS STRIPLINE STRUCTURE USING AN EFFICIENT INTERIOR EXTERIOR GREENS-FUNCTION METHOD

An accurate and efficient technique is developed to calculate the curr ent distribution over the cross-section and close to the corners of a high-temperature superconducting (HTS) strip in a stripline structure. The problem is formulated in terms of a set of coupled integral equat ions for the axial electric field inside and outside of the strip, An accurate and fast converging complex images Green's function is derive d for the exterior region, Numerical results are presented for a typic al HTS stripline. Non-singular behaviour of the current density distri bution close to the corners is demonstrated.
