Tried to run model, but Comsol requests Plasma Module, which I don't have.

1) The uploaded model is created in COMSOL 4.0a and as such it must be opened with COMSOL 4.0a or later.
2) The model requires the AC/DC or Plasma module.

Hi,
In this example you are using a Copper plate with a relative permittivity of 1 while Copper and all other metals have a complex (rather purely imaginary dielectric constants). Please clear this dilemma for me as I am stuck in this for the last one month or so. In forums they suggest some solutions that are not relevant to my case e.g. "http://www.comsol.nl/community/forums/general/thread/6809/"
On this forum, I have posted a comment query with explanation of the problem that I am trying to solve. I am actually solving an electrostatic induction problem (no involvement of any frequency) while the texts that I have read say that the complex dielectric constant is a function of frequency. Please, reply to my query.

Hellow,
I do have comsol 4 and I still can't open this model.
It says it has no model
DO you have any suggestions?
