    Graduate Permeability of copper in the microwave frequency range

    When I was doing google search before the post I saw this one too. It was a long time ago when I studied electrodynamics but if I remember correctly there is a problem with using Drude model for diamagnetics because of Kramers - Kroning relations.

    Graduate Permeability of copper in the microwave frequency range

    Relative DC permeability of copper is 1. Conductors are considered dispersive and therefore the permeability should change with frequency. Where can I find data or how can I calculate permeability of copper in Ghz frequency range?

    Graduate Amount of charge stored by thin conductive plate

    Thank you. Conductive coating that I'm using is doped tin oxide. Undoped tin oxide is a dielectric with K of 9.8. It's probably lower for doped material. In theory I'm adding a layer of dielectric on the top of dielectric film. This should after the capacitance because of series capacitance of...

    Graduate Amount of charge stored by thin conductive plate

    I have 10mm thick film with dielectric constant of 3. Let’s say surface area of the film is 50 ft2. On the surface of the film I will deposit thin conductive layers with different resistivity. On the first sample of the film I will deposit thin layer with the sheet resistance of 10...
