Modelling Split Ring Resonator in MWS

Hi, I am new to using MWS and am not too sure how to go about testing various designs & layouts of split ring resonators. I believe I should be looking into investigating transmission properties, and looking for a strong drop-off at a frequency where the SRR resonates, but don't know how to do this. Can anyone help, or point me in the direction of a tutorial or two please?
Thanks in advance
