RFID modelling

Please login with a confirmed email address before reporting spam

Hello,

I have been using COMSOL for about 3 days and and so I'm a complete beginner to it. I am looking for some general advice about modelling an RFID system. Specifically, what I want to do is have an RFID transponder coil just above a metallic plate and the reader coil a few centimetres above the tag. I would like to investigate the effect of different metal types on the impedance of the transponder coil and the reader coil.
I have found the following model but having some difficulty modifying it to get some useful results.

If anyone has done any RFID modelling or can offer some general guidance it would be very much appreciated.

Update: I have a more specific request. Has anyone used the RFID model from the link above? If so do you know how I can measure the impedance/resistance of the transponder coil?
