Dispersive Materials in Transient Electromagnetic Waves module

I'm quite new to Comsol and I'd ask for your advice on the the following topic:
I'm using a Transient Electromagnetic Waves study (RF module) in order to model a short Gaussian pulse impinging on a metallic device. Since I want to study the plasmonic effects that are generated I need to include dispersive effect due to a frequency dependent dielectric function.
Since from what I understood dispersive material are built in in TEW, I' m trying to use an ADE model, i.e. I include an equation for the polarization of the material and I solve the equation together. To do that I add some equation to describe the differential equation for the polarization via right-click Model 1 > Add Physics and that I choose Coefficient PDE. Is it the right way to do it?
Now doing that way, I get no error, apart that the computation blocks at the first time step and doesn't proceed anymore. To quit, I have to kill the job.
Any idea about the problem?
Thanks in advance,
Mattia
