    Viewing surface current in CST microwave studio 2009

    Dear zuboraj, To plot the surface currents you have to set a filed monitor (choosing surface current as the variable to observe) at the desired frequency. Hope it could help. iaia

    TEM mode with a waveguide port in CST

    tem mode in waveguide Hi, You should set a waveguide simulator with two opposite magnetic walls parallel to the electric field and the other two walls as electric walls. Then, put waveguide ports where you want the plane wave to incide. Regards, Iaia

    absorbing condition in COMSOL

    absorbing boundary comsol Hi all, I need to simulate an infinite (in the y direction) dielectric slab with finite width (in the x direction) in COMSOL and see the scattering field, but I do not know how to set the absorbing boundary condition at the edges of the slab. Does anyone know how to...

    CST - material with continual changing permitivity

    Re: CST - change permitivity Use COMSOL: there you can use an anisotropic and inhomogeneus material.

    how many frequency samples are enough

    Hi, I have changed this value up to 100001 which is the maximum value choosable. My results were completely different changing this value, but I was simulating a resonant structure with very thin resonances so I needed a high frequency precision. Anyway, in my opinion you should always do a...

    Which is the best simulator: COMSOl or CST?

    comsol cst ads ansys Hi all, I need to simulate a monomodal applicator in a rectangular waveguide for the purpose of microwave heating (so I need to solve, among other things, the heat equation). Which is the best simulator: COMSOl or CST? Any advice or suggestion would be very appreciated. Thanks

    Help me with source field in COMSOL (a constant identity)

    matched boundary comsol Hi all, I am using the TE InPlane waves Electromagnetic module in COMSOL and I need to specify the amplitude of the incident electric field E0z. When I put 1 in the corresponding matched boundary condition field, the results of my simulation suggest that Comsol...
