How to display current density in thin metallic layer difined by transition boundary condition

Please login with a confirmed email address before reporting spam

Hi to all,

I'm working with the RF module to simulate response of metamaterial which consists of split ring resonator (SRR). The SRR is made of thin metallic layer. To model the layer within Comsol I'm using the Transition boundary condition.
I want to know current density in thin metallic layer. Here there are some questions:

I succeeded computing transmittance (emw.S21) and the results was good agreement with my experimental results. It was good. But Current densities do not appears. Do you have idea on how to display current densities?

Thanks for the answers.

A.I.

Hi,

The norm of the surface current densities on the two sides of the Transition Boundary Condition are called emw.normJs1 and emw.normJs2, respectively. You also find the surface current density components as emw.Js1[x,y,z] and emw.Js2[x,y,z]. These entries are available under "Currents and charge" in the plot menu.

Best regards,

Ulf
