Coupling games in metamaterials

چکیده
Metamaterials have become one of the hottest fields of photonics since the pioneering work of John Pendry on negative refractive index, invisibility cloaking, and perfect lensing. For practical applications, three-dimensional metamaterials are required. Here, coupling effects between individual constituents play a dominant role for the optical and electronic properties. Metamaterials can offer both electric and magnetic responses at optical frequencies. Hence, electric as well as magnetic dipolar and higher-order multipolar coupling are the essential mechanisms. The intricate interplay between different coupling effects in a plasmon hybridization picture provides a hands-on tool to intuitively understand the evolution from moleculelike states to solid-state-like bands.

Optical Möbius symmetry in metamaterials.
We experimentally observed a new topological symmetry in optical composites, namely, metamaterials. While it is not found yet in nature materials, the electromagnetic Möbius symmetry discovered in metamaterials is equivalent to the structural symmetry of a Möbius strip, with the number of twists controlled by the sign change of the electromagnetic coupling between the meta-atoms. We further dem...

The acoustic wave velocity depends on elasticity and density at most materials, but because of anisotropy and especially piezoelectric coupling effect, the acoustic wave propagation at piezoelectric based crystalloacoustic materials, is an applied and challenging problem. In this paper, using modified Christoffel's equation based on group velocity concept, the effect of anisotropy and piezoelec...
متن کاملMechanism of the metallic metamaterials coupled to the gain material.
We present evidence of strong coupling between the gain material and the metallic metamaterials. It is of vital importance to understand the mechanism of the coupling of metamaterials with the gain medium. Using a four-level gain system, the numerical pump-probe experiments are performed in several configurations (split-ring resonators (SRRs), inverse SRRs and fishnets) of metamaterials, demons...
متن کاملAnomalous optical coupling between two silicon wires of a slot waveguide in epsilon-near-zero metamaterials
Anomalous optical coupling properties between two silicon wires in a silicon slot waveguide embedded in epsilon-near-zero (ENZ) metamaterials are proposed and demonstrated. The dependences of optical field enhancement in the slot region and transverse optical force on the slot size and the permittivity of surrounding material are studied in details. It is demonstrated that the optical field in ...
متن کاملCoupled-resonator-based metamaterials
In this review, we describe recent developments in functional metamaterials based on coupled resonators. We first consider coupled resonator metamaterials that mimic electromagnetically induced transparency (EIT). We present a circuit model for EIT-like metamaterials and introduce a new coupled resonator in which the coupling is provided by a field gradient so that the group velocity can be var...
