We study wire metamaterial consisting of two displaced nonconnected metallic networks. This double interlaced wire metamaterial supports no-cutoff isotropic longitudinal modes at low frequencies, which are bulk plasmons of the medium with extremely high spatial dispersion. In our report some results of our work will be presented, we’ll dwell on dispersion properties of such metamaterial and discuss an influence of symmetry breaking in the unit-cell geometry at them.
