چکیده

increasing development of nano-technology in optics and photonics by using modern methods of light control in waveguide devices and requiring miniaturization and electromagnetic devices such as antennas, transmission and storage as well as improvement in the electromagnetic tool, have led researchers to use the phenomenon of electromagnetically induced transparency (eit) and similar phenomena in metamaterials. in this work, we introduce a metamaterial structure in nanometer dimensions and thz frequency region. moreover, by broking the geometrical symmetry structure, we offer eit with high transmittance and more q-factor in comparison, to our knowledge, with previous studies of two-dimensional structure, in the infrared region. these achievements can be a good choice for slow light applications and can be used to amplify light in nanostructure and also to detect the infrared light. finally, we study the effect of changing the metal on the proposed metamaterial. moreover, in this study, numerical calculations and simulations are done by fdtd method.

Low-loss metamaterials based on classical electromagnetically induced transparency.

We demonstrate theoretically that electromagnetically induced transparency can be achieved in metamaterials, in which electromagnetic radiation is interacting resonantly with mesoscopic oscillators rather than with atoms. We describe novel metamaterial designs that can support a full dark resonant state upon interaction with an electromagnetic beam and we present results of its frequency-depend...

Active control of electromagnetically induced transparency analogue in terahertz metamaterials.

Recently reported metamaterial analogues of electromagnetically induced transparency enable a unique route to endow classical optical structures with aspects of quantum optical systems. This method opens up many fascinating prospects on novel optical components, such as slow light units, highly sensitive sensors and nonlinear devices. In particular, optical control of electromagnetically induce...

Planar designs for electromagnetically induced transparency in metamaterials.

We present a planar design of a metamaterial exhibiting electromagnetically induced transparency that is amenable to experimental verification in the microwave frequency band. The design is based on the coupling of a split-ring resonator with a cut-wire in the same plane. We investigate the sensitivity of the parameters of the transmission window on the coupling strength and on the circuit elem...

Handedness Dependent Electromagnetically Induced Transparency in Hybrid Chiral Metamaterials

We provide the first experimental demonstration of the handedness dependent electromagnetically induced transparency (EIT) in chiral metamaterials during the interaction with circularly polarized waves. The observed chiral-sensitive EIT phenomena arise from the coherent excitation of a non-radiative mode in the component split ring resonators (SRRs) produced by the corresponding Born-Kuhn type ...
