Structural tunability in metamaterials
Mikhail Lapine, David Powell, Maxim Gorkunov +3
We propose a novel approach for efficient tuning of the transmission characteristics of metamaterials through a continuous adjustment of the lattice structure, and confirm it exper…
Ferroelectric ordering in chiral smectic C^* liquid crystals determined by nonchiral intermolecular interactions
M. A. Osipov, M. V. Gorkunov
General microscopic mechanism of ferroelectric ordering in chiral smectic C* liquid crystals is considered. It is shown that if the mesogenic molecules have a sufficiently low symm…
Tunability of wire-grid metamaterial immersed into nematic liquid crystal
M. V. Gorkunov, M. A. Osipov
We propose electrically tunable hybrid metamaterial consisting of special wire grid immersed into nematic liquid crystal. The plasma-like permittivity of the structure can be subst…
Molecular model for de Vries type smectic A - smectic C phase transition in liquid crystals
M. V. Gorkunov, M. A. Osipov, F. Giesselmann +2
We develop a theory of Smectic A - Smectic C phase transition with anomalously weak smectic layer contraction. We construct a phenomenological description of this transition by gen…
Eigen modes for the problem of anomalous light transmission through subwavelength holes
B. Sturman, E. Podivilov, M. Gorkunov
We show that the wide-spread concept of optical eigen modes in lossless waveguide structures, which assumes the separation on propagating and evanescent modes, fails in the case of…
Suppressed absolute negative conductance and generation of high-frequency radiation in semiconductor superlattices
Kirill N. Alekseev, Maxim V. Gorkunov, Natalia V. Demarina +3
We show that space-charge instabilities (electric field domains) in semiconductor superlattices are the attribute of absolute negative conductance induced by small constant and lar…
