    Discussion:Resonance frequency of transmission line w/o PMC

    resonance in a transmission line I have met a problem recently and hope experts can give me some hints. You can find the resonance frequencies from the S parameter curves of a transmission line (eg. microstrip line as shown in the following figures). When both sides of the transmission line...

    How to detect the time signal convergence automatically

    I am working on the FDTD solver coding. You know, when using FDTD to calculate the S parameter, we should stop the simulation when the time signal converges. As a solver, it should have the ability to automatically detect the convergence and stop a simulation at convergence. Thus users do not...

    A question on rational functional approximation

    How to approximate the following function s/√(s²+p²) with Σ{ai/(s-bi)}? I know vector fitting can work, but it's too complicated.:| Is there any shortcut or easy way for this approximation? Thanks a lot! :D
