in a research experiment to fabricate metamaterial, what is the procedure to determine both mu and epsilon, especially the mu and epsilon near zero (MENZ)?
This is called parameter retrieval or homogenization. You can watch a video here that is a quick introduction here in Lecture 15:

Thank you so much Raymond, the material you have provided are very helpful. The procedure has opened my eyes to a different world. Thank you Sir.
Hello Edgar,
There are several methods to do it. But the most common is the calculating reflection and transmission coefficients, scaterring matrix. So, if you have reflection and transmission coefficients, you can calculate refractive index and impedance. Using these parameters you can define effective permittivity and permeability. You can find more information and formulas in this article (http://journals.aps.org/prb/abstract/10.1103/PhysRevB.65.195104), for example. Good luck!
