Pseudo-planar conjugated swastikas metamaterial with giant circular dichroism and negative refraction at near-infrared region

Abstract: In this paper, a pseudo-planar conjugated swastikas metamaterial (MM) was proposed and investigated numerically at near-infrared region. Numerical results show that the circular dichroism (CD) is more than 25 dB at resonance frequencies. Owing to the stronger chirality, the refractive indices for right-handed and left-handed circularly polarized waves are negative. The surface current distributions are studied to explain mechanism of the chiral behaviors. The pseudoplanar MM is easy to fabricate and thus lead … Show more

“…This is because each ring can be regarded as an LC oscillatory circuit, thereby forming an electric dipole for the transmission of electric energy, the coupling of adjacent rings forms a magnetic dipole for the transmission of magnetic energy. Under these conditions, the magnetic field energy is LQ ′2 /2 and the electric field energy is Q 2 /2C [5]. When α and g are increased, this makes the inductance L, capacitance C, and the electrical charge Q all increase, which means that the magnetic field energy and electric field energy increase as well.…”

“…Ref. [2,3,4,5,6,7,8,9,10,11] CMMs with self-polarization and cross-polarization between electromagnetic fields can achieve a negative index of refraction depending on their chirality, whether or not the permittivity and permeability are negative. Furthermore, they can exhibit strong optical activity and lower loss of the electromagnetic wave (EMW) transmission.…”
