COMSOL Help

[sayhitoarya]

Hi All,

I am pretty new to COMSOL. I want design model of a sensor with four electrode. This sensor mainly based on impedance spectroscopy principle. The model should measure the distance and thickness of the obstacle due to change in capacitive impedance of electrostatic field between the dipoles.

Can anybody help regarding this, how to start in which mode of electromagnetics?

Is the problem stationary (or time-independent enough)? Would think conductive media DC or electrostatics. I'm going to have to refresh myself concerning impedance spectroscopy principle.
