You can specify the relative permittivity of a material under the material properties.
Component --> Materials --> etc. I suggest you consult the Comsol Multiphysics Help system and/or study the examples in the supplied Application Library, to see how this is done. If you have data in the form of a table, you may wish to import it and create an interpolation function to go with that data. You can then use that interpolation function in your specification of the material's permittivity.
