what is the procedure for finding the right dielectric material and metal when intending to obtain near zero permeability metamaterial (MNZ)?

06 April 2015 1 10K Report

Differernt papers show the use of different materials for simulations to obtain zero index metamaterial, is there some kind of a guide in choosing the dielectrics and metals?
