Summary: In this study, we analyze the band structure of a single-phase metamaterial involving low-frequency flexural resonances by combining asymptotic homogenization and Bloch-Floquet analysis. We provide a closed-form expression of the dispersion relation in the whole Brillouin zone and demonstrate the existence of band-gaps and negative refraction in the hyperbolic regions of the dispersion diagram at low frequencies. Our findings are validated through direct numerical calculations.

Summary: By periodically introducing plasma layers into a one-dimensional photonic crystal, researchers have successfully broadened the photonic band gap, achieving an ultra-large omnidirectional photonic band gap width of up to 1321 nm. This simple structure could be utilized to design ultra-broadband optical mirrors and narrowband optical filters with ultra-large omnidirectional stopbands.

Summary: This study investigates the impact of spatial dispersion on propagation properties of planar waveguides with hyperbolic metamaterial (HMM) core layer. By altering the dimensions of the unit cells, new effects such as mode degeneration, power flow inversion, propagation gap, and plasmonic-like modes were observed. Additionally, unique characteristic points for high-beta TM mode were reported for the first time, showing power flow approaching zero and mode stopping at a specific waveguide width.

Summary: In this study, approximate equations for the conductivity of metal nanowires and thin films are obtained within the Landauer-Datta-Lundstrom model. These equations are useful for determining the conductivity of nanostructures and calculating the number of conduction modes and energy levels of quantum wires with finite transverse dimensions. The solution to the problem of a Zenneck-Sommerfeld wave in a rectangular wire, which transforms into a surface plasmon at high frequencies, is significantly influenced by changes in the plasma frequency associated with transverse dimensions.

Summary: In this study, we analyze the radiative heat transfer between two parallel and infinitely long carbon nanotubes (CNTs). Our findings show that the radiative heat transfer depends not only on the distance between the nanotubes, but also on their chiralities and thus on their semiconducting or metallic nature, providing the possibility to design nanostructures for optimal radiative heat exchange.

Summary: This article considers methods of inversion of integrodifferential operators of thin linear antennas and the dispersion interaction of the Casimir-Lifshitz force between two thin linear objects described by the dielectric constant in the form of Drude-Lorentz. A new rigorous model based on the Lorentz force is proposed to calculate the Casimir-Lifshitz forces for thin dielectric or conductive filaments. The correlations are determined using the formulas of G.T. Markov, the fluctuation-dissipation theorem, and the principle of detailed equilibrium with a thermal field. Analytical estimates of the obtained spectral integrals are performed in the far zone.
