Volumetric metamaterials with a regular structure can have elemental structural cells that translation along coordinate axes simulates the entire structure of macroscopic sample. If there are elements in this metamaterial that are responsible for electrical and magnetic properties, then we can say that this is an electromagnetic crystal. Samples that electrical (effective permittivity) properties are determined by long conductors, and magnetic ones - by half-wave vibrators, were investigated. Measurements of transparency spectra and forbidden electromagnetic band gap were carried out in the frequency range of 8 - 12 GHz. Measurements of refractive index in the material were carried out on the angular deviation of microwave radiation passing through a prism. Measurements show that samples with the same structure (unit cell) can significantly change their characteristics even with a small change in one of the internal parameters of the cell.
