investigate the material and geometry dependent resonances of metallic nano-particles

Hello everyone,

In my project, I added interpolation for relative permittivity and loss tangent. I want to get the relative permittivity and permeabilility. I did some things, and after adding electric field I need to get a plot but I can't get plot but I can't see anything. What is my problem? Anyone can help me? I get error while uploading the project, I am attaching the pics. These pics are what I changed after open newly.

Thanks
