Abstract :
A singular value decomposition (SVD) based numerical approach was used to solve ill-conditioned matrix equations resulting from circuit analysis with periodic Bloch conditions for 2D distributed periodic structures. The method allows modelling of dissipative lumped elements, transmission lines, and inclusion of nonlinear elements
