Which root finding method is proper for obtaining dispersion diagram of cylindrical infinite nanowire from its dispersion equation?

I am trying to numerically find roots of an infinite metallic nanowire to plot dispersion diagram. I write a "for" loop in MATLAB, and set frequency value at each time, and then proceed to find...

How to obtain S parameters of a ridge waveguide in HFSS?

I want to obtain the S parameters of a ridge waveguide in HFSS by putting two waveports at the two ends of the waveguide. But the S21 becomes so small (about -10dB). I think it is probably due to...

How to export all tables obtained from parameter sweep in CST together?

I have simulated a waveguide structure in CST with the eigenmode solver. Each resulting table is related to a mode and I want to plot the dispersion diagram in MATLAB. But it seems impossible to...
