“…In our system, each cut wire alone can directly couple electromagnetic wave under the excitation of the incident wave. Therefore, in our case, the induced EITlike effect results from the coupling between the bright and bright modes, which is widely considered as a method for construction of the EIT-like metamaterial [8,15,17,18,20,26]. However, this is different from the classical EIT-like scheme, where the dark mode cannot be directly excited by the incident wave and responds indirectly though the coupling with the bright mode [13,16].…”

“…This is because the antiparallel currents on the cut wires cause the destructive interference of the scattering EM fields, so that the radiation fields of wires I and II are greatly suppressed when the wire III exists. These striking features indicate that this metamaterial represents a promising candidate toward achieving the slow light, the biologic sensor and the low loss [19][20][21].…”

“…The EIT refers to the formation of a transmission window inside the absorption band of a three-level atomic media, in which two laser beams are resonantly coupled to two energy level transitions with different relaxation times [13]. Recently, a lot of attention has been paid to the fact that the EIT-like effect can occur in many classical oscillator systems [14][15][16][17][18][19][20][21][22]. Particularly, metamaterials are also configured to obtain the EIT-like effect.…”

The influence of symmetry breaking in a planar metamaterial on transparency effect is numerically investigated. The planar metamaterial's cell is formed by three parallel metal wires. From numerical simulation results, we can see that the transparency effect results from the asymmetric coupling between the cut wires. The excited mechanism of the transparency effect is further analyzed by using the hybridization concept. It is found that the coupling fields between the cut wires play key roles and lead to the spectral splitting of the resonance, i.e., the classical electromagnetically induced transparency effect. The metamaterial sensor based on the refractive index variation of the surrounding material is also numerically demonstrated and yields a sensitivity of 9.47 mm/RIU and a figure of merit of 13.5. In addition, the spectral response of the metamaterial is quantitatively described via the "three-particle" model. The analytically calculated results of the model show a good agreement with the simulation results.

“…Specially, the analogues of EIT effects in metamaterials have received great attention by scientific communities. [9][10][11][12][13][14][15][16][17] However, most of these works rely on the electric interactions between different resonators. Only few works are related to the magnetic interactions.…”

“…Since the magnetic dipole of bright resonator is almost vanishing, the coupling strength of the EIT structure to incident EM wave is rather weak, leading to a high transmission, which is extremely important for the applications of slow lights and low loss devices. 14,16 A striking effect associated with EIT is its strong dispersion in transparent window, which is the key to reduce the group velocity. As illustrated in Fig.…”

In this paper, a broadband plasmon-induced transparency (PIT) hybrid metamaterial system (HMS) is realized and numerically demonstrated via the interference between different resonance modes of metal and dielectric resonators. The employed PIT HMS supports a strong near-fired coupling between unit cells consisting of eight TiO 2 nested split rings (dark plasmonic resonators) surrounded by four metal cut wires (bright plasmonic resonators) embedded in the intermediate dielectric layer, and a broad transparency window which is higher than 0.9 is obtained from 0.61 to 0.76 THz with a relative bandwidth of 21.9%. In the transparent window, the drastic change of phase leads to high group delay, and the remarkable slow light phenomenon can be clearly observed. The maximum of the group delay and group index can reach 528 ps and 2880, respectively. The localization distributions of the electromagnetic field intuitively exhibit the generation and action process of destructive interference. The theoretical investigation of the two-oscillator model further confirms the effectiveness and consistency of the simulation results. In addition, the fourfold symmetric of the proposed PIT HMS supports the liberation from the dependence of incident polarization form. Such an implementation opens a new path for the designing of filtering, switching, and data storing devices.
