Coupling projection domain decomposition method and Kansa's method in electrostatic problems

This paper present a novel approach for solving electrostatic problems associated with an asymmetrical shielded stripline and shielded coupled-striplines. This novel approach is based on combination of radial basis functions-based meshless unsymmetric collocation method (also, Kansa's method) with projection domain decomposition method. Under this new method, we just need to solve a Steklov–Poincaré interface equation and the original problem is solved by computing a series of independent subproblems. Two real problems are solved by the proposed approach to demonstrate the accuracy and efficiency.
