Transmission properties in chiral metamaterials
Transmission properties of chiral metamaterials are investigated through the loss factor. Besides the amplitudes of transmission coefficients of right and left circularly polarized waves, the phases are the other main keys to control the refractive index and chirality of the chiral media, directly affecting the loss factor (LF). The LF is low when the phase combination of circular waves is larg...
متن کاملOptically controllable THz chiral metamaterials.
Switchable and tunable chiral metamaterial response is numerically demonstrated here in different uniaxial chiral metamaterial structures operating in the THz regime. The structures are based on the bi-layer conductor design and the tunable/switchable response is achieved by replacing parts of the metallic components of the structures by photoconducting Si, which can be transformed from an insu...
متن کاملCasimir Forces in Chiral Metamaterials
We use the extended Lifshitz theory to study the behavior of the Casimir forces between chiral metamaterials and regular metamaterials. We have shown that the chirality, if strong enough, is of critical importance to reduce the Cassimir attractive force and can find new designs to obtain repulsive Casimir forces. We will review chiral metamaterials and find some analytical expression for the st...
متن کاملChiral phenomena in toroidal metamaterials
We present the first observation of circular dichroism due to a combination of resonant toroidal dipole and electric quadrupole excitations in a toroidal metamaterial.
متن کاملCircular dichroism of planar chiral magnetic metamaterials.
We propose, fabricate, and study a double-layer chiral planar metamaterial that exhibits pronounced circular dichroism at near-infrared wavelengths. The antisymmetric oscillation modes of the two coupled layers allow local magnetic-dipole moments and enhanced polarization effects compared with similar single-layer systems where only electric-dipole moments occur. Experiment and rigorous theoret...
