Nikolay Pavlov I am talking about both simulation. And you are right we need periodic boundary conditions.Please let me know how I perform these simulation in hfss ?
Dear Vivek Prakash Yadav , as the first step you can use the example of SRR unit, which was proposed in the Library of typical samples that were included in HFSS distributive. You can read the white paper of the Ansys developer regarding the calculation of SRR unit parameters.
Typical results of this approach can see here:

If you know how to use COMSOL or a transfer matrix code, in that case, you may find useful my paper that explains how to design metamaterials with specific optical features
Vivek Prakash Yadav i do feel that the Design and Analysis of Two Novel Metamaterial Unit Cell for Antenna Engineering needs to be looked at and the link I have shared here with gives u a perfect picture about the same and hope this is useful to you

One more similar paper publication I came across ResearchGate related to Evaluation of metamaterial unit cell analysis techniques and this is in line with your query as well
