Power handling capability of a HTS stripline structure using an efficient interior-exterior Green's function method

摘要

An accurate and efficient technique is developed to calculate the current 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 equations for the axial electric field inside and outside of the strip. An accurate and fast converging complex images Green's function is derived for the exterior region. Numerical results are presented for a typical HTS stripline. Non-singular behaviour of the current density distribution close to the corners is demonstrated.
