    Strange transmission curves in HFSS for a particular substance at a very specific thickness

    Basically, HFSS doesn't know what the material is made up of. The dielectric is defined by the real and imaginary component of the permittivity in the 100GHz range, where the dielectric loss tangent is epsilon_Re/epsilon_Im

    Strange transmission curves in HFSS for a particular substance at a very specific thickness

    Ok, so I have simulated some transmission curves for different powders modeled as dielectric clads. The screenshot taken from excel shows all of the ones that are nice and smooth (at 50um here, but remain nice and smooth regardless of thickness within my limits). The problem comes when I try to...

    Checkerboard shaped Artificial Magnetic Conductor array in HFSS or CST - Get RCS

    So I have a checkerboard shaped array whose shape is of the form: 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 The surface of 1s and 0s sits atop a 1.4mm dielectric medium that is backed by a PEC, where the 1s represent...
