Monoclinic-symmetry photonic crystals assembled from identically oriented copper wire split rings are found to manifest photon nontransmission bands related to the electric and magnetic dipole excitations of the interacting oscillators. The width and form of the bands are shown to depend on photon polarization and propagation direction with respect to the crystal axes. The single split-ring resonance lines are shown for comparison. The ring diameter and the crystal lattice constant are significantly less than the electromagnetic wavelength. Experimental data are compared to the mean-field model including the series of oscillator functions for electric and magnetic polarization.

    The added masses of a monopole and a dipole placed in a narrow pipe are studied experimentally. It is shown that, when a monopole passes from a free space into a narrow pipe, its added mass decreases, whereas the added mass of a dipole in a similar situation increases. Inside the pipe, for both...

    The processes of generation of disclination dipoles and nanoscopic cracks (nanocracks) in deformed nanoceramic materials are investigated theoretically. It is demonstrated that disclination dipoles are formed at grain boundaries in the course of grain-boundary sliding. The geometric features of...
