Need metamaterial example for COMSOL with nonlinear property exploration

hi
can anyone help me getting some example for running metamaterial simulation in COMSOL with nonlinear property exploration. i like to determine the SHG and THG efficiency of the metamaterial.

Hello,

Didn't you find some examples in the COMSOL website tutorials section ? (you need to login)

no there is no tutorial about to find efficiency of non linear generation. do you use COMSOL. i have just started to learn it. do you have basic model of metamaterial in COMSOL?

Me too, looking for LHMs and Comsol... I may help you later, if i learn it of course

I also work in this field. But I still have no any progress about it!
