Abstract: In this paper we consider the electromagnetic crystal consisting of long, straight wires (rods) forming a two-dimensional square lattice in the dielectric matrix. It is shown that the crystal in a small band is like a quasi-homogeneous medium with simultaneously negative electrical and magnetic permeabilities. The effect of negative refraction at microwave frequencies is demonstrated. The frequency ranges in which the electromagnetic crystal exhibits the effects of positive and negative refraction, corresponds to band structure obtained numerically and experimentally.
