(01) Simple Dipole Step by Step - COMSOL 4.2 Tutorial

[gustavolsilvano]

Hi there. Your videos were very interesting, and helped me in my models. But I'm having a problem when trying to simulate a nanodiopole with a lumped port between them. What I seek is the lumped port impedance and the s-parameter. When I simulate a dipole in meters scale and with MHz frequency, it leads me the right answer, but when I use a nano scale and THz, then it leads me to a very small input impedance. For the boundary condition, I just use a sphere with the scattering codition.
