Electro-optical switching by liquid-crystal controlled metasurfaces
Manuel Decker, Christian Kremers, Alexander Minovich +6
We study the optical response of a metamaterial surface created by a lattice of split-ring resonators covered with a nematic liquid crystal and demonstrate millisecond timescale sw…
Plasmonic nanoparticle monomers and dimers: From nano-antennas to chiral metamaterials
Dmitry N. Chigrin, Christian Kremers, Sergei V. Zhukovsky
We review the basic physics behind light interaction with plasmonic nanoparticles. The theoretical foundations of light scattering on one metallic particle (a plasmonic monomer) an…
Plasmonic rod dimers as elementary planar chiral meta-atoms
Sergei V. Zhukovsky, Christian Kremers, Dmitry N. Chigrin
Electromagnetic response of metallic rod dimers is theoretically calculated for arbitrary planar arrangement of rods in the dimer. It is shown that dimers without an in-plane symme…
Light Scattering on Nanowire Antennas: A Semi-Analytical Approach
Christian Kremers, Dmitry N. Chigrin
Two semi-analytical approaches to solve the problem of light scattering on nanowire antennas are developed and compared. The derivation is based on the exact solution of the plane…
Spatial distribution of Cherenkov radiation in periodic dielectric media
Christian Kremers, Dmitry N. Chigrin
The nontrivial dispersion relation of a periodic medium affects both the spectral and the spatial distribution of Cherenkov radiation. We present a theory of the spatial distributi…
Theory of Cherenkov radiation in periodic dielectric media: Emission spectrum
Christian Kremers, Dmitry N. Chigrin, Johann Kroha
The Cherenkov radiation is substantially modified in the presence of a medium with a nontrivial dispersion relation. We consider Cherenkov emission spectra of a point charge moving…
