We consider an array of the meta-atom consisting of two cut-wires and a split-ring resonator coupled with an electromagnetic field with two polarization components. We show that the system can be taken as a classical analogue of the atomic medium of a double-Λ-type four-level configuration coupled with four laser fields and working under the condition of electromagnetically induced transparency, exhibits an effect of plasmon induced transparency (PIT), and displays a similar behavior of atomic four-wave mixing (FWM). We show also that with the PIT and FWM effects the system can support vector plasmonic dromions when a nonlinear varactor is mounted onto the each gap of the split-ring resonator. Our work not only gives a plasmonic analogue of the FWM in coherent atomic systems but also provides the possibility for obtaining new type of plasmonic excitations in metamaterials.

“…Metamaterials composed of two radiative resonators coupled with each other have also been shown to exhibit EIT-like responses [14][15][16][17]. In addition to these fundamental demonstrations of EIT-like metamaterials, active control of electromagnetic responses [18][19][20][21][22][23][24][25] and enhancement of nonlinear phenomena [26][27][28][29][30] in EIT-like metamaterials have also been investigated. Furthermore, storage and retrieval of electro-magnetic pulse waves have been demonstrated using EIT-like metamaterials [31,32] as demonstrated using the original EIT.…”

We develop a method to control the group delay of electromagnetic waves continuously using a doubly resonant metasurface. The method is based on the dependences of i) the group velocity in a medium featuring two resonance lines on the resonance linewidths and ii) the resonance linewidth of a metasurface composed of split-ring resonators on an incidence angle of electromagnetic wave. To verify this method for group-delay control, we design a terahertz metasurface composed of two split-ring resonators with different resonance frequencies and numerically analyze the transmission characteristic of the metasurface. Double resonance lines are observed for oblique incidence and the resonance transmission dips become deeper and broader with increasing the incidence angle. The group delay at around the center frequency of the double resonance lines is found to vary in the range about from 0 s to 20 times the period of the incident wave with the incidence angle. In contrast with a previously reported method for variable control of group delay using electromagnetically-induced-transparency-like metamaterials, a high transmittance is achieved for a small group delay condition.

phenomena of metamaterials could be utilized for optical devices, such as slow light device, [10][11][12][13][14] nonlinear optics, [15][16][17] or novel optical sensors. [18][19][20][21] However, conventional EIT analogues from these metamaterials could be generated only by the destructive interference between asymmetrically split two half-rings or between bright and dark meta-atoms to produce the sharp transmission peak within the refl ection spectral window. For this reason, though the sharp transmission peak could be formed at the specifi c refl ective spectrum due to their origins of the destructive interference, these EIT analogues merely transmitted the light from their 2D or 3D array structures without focusing or enhancement of the incident light.In this paper, we proposed a new way to achieve EIT-like spectral properties from a single self-complimentary terahertz meta-atom by integrating cut-wire pair with a pseudo-complimentary cut-wire structure within a unit cell. Different from the conventional EIT analogues using the destructive interference between bright and dark meta-atoms, the induced current by the incident THz wave could generate a localized magnetic fi eld (H-fi eld) inside the hole of the pseudo-complimentary cut-wire, and accordingly electric fi eld (E-fi eld) was highly enhanced and focused at edges of the hole to achieve EIT-like properties in the proposed self-complimentary meta-atom structure.Therefore, by exciting both cut-wire and its complimentary components unifi ed in our self-complimentary single metaatom simultaneously with the incident THz wave, we showed that the EIT-like spectral properties could be achieved through the localized H-fi eld at the resonance which could focus E-fi elds out of the orthogonally placed cut-wires into the hole of the pseudo-complimentary cut-wire in a unit cell. Note that since the complimentary cut-wire structure in the proposed metaatom was not formed as the hole on the full metal sheet but was formed by being surrounded by cut-wires, it was named as the pseudo-complementary cut-wire. The detailed effects of the cut-wire width on the spectral properties were discussed in the Supporting Information. Design and Analysis of Self-Complementary Meta-AtomAs shown in Figure 1 , we prepared a cut-wire (CW) pair and pseudo-complementary cut-wire (p-CCW) pattern, andIn the past years, many researchers have tried to realize the electromagnetically induced transparency (EIT) phenomena from the metamaterial arrays for the attractable applications such as slow light devices, novel optical communication systems, and nonlinear optical devices. Most of metamaterial enabled EIT analogues reported so far are based on the destructive interference between the bright and dark meta-atoms. Whether they are located on the same plane or off the plane, EIT-like properties can be achieved only by breaking the symmetry between the bright and dark meta-atoms. In this study, a novel self-complimentary terahertz meta-atom is developed by combining cut-wire resonators and its pse...
