“…From these data, we can see that the space between two adjacent units will only slightly influence the frequency of the resonances. For larger periods the frequencies of the first and second resonances increase for larger periods, which can be explained by the reduced interaction of two neighboring MM units parallel to the E-field (polarization along yaxis) [36]. For the third resonance, whose contribution part is the central-arm, the resonance frequency is basically independent of the periodicity, which might be explained by a shielding effect of the two side-arms that prevents interaction between the MM units.…”

Abstract-We propose two metamaterials with sub-wavelength double-slots -single-side double-slot metamaterial and double-side double-slot metamaterial. The dependence of the electromagnetic resonances and local intensity enhancements on the structural parameters is studied by the finite-difference time-domain technique and the finite element method. Results show that the central-arm of a double-slot structure strongly influences frequency and local intensities at both high-and low-frequency resonances. Very strong field localization can be achieved at the high-frequency resonance and its particular distribution can be well controlled by the width of the central-arm. A double-side double-slot structure can be utilized to separately enhance the high-frequency resonance, while suppressing the low-frequency resonance. The simulation results are discussed in terms of plasmon resonances.

“…This set-up will increase the total capacitance value as C total = C gap + C parallel . In references [30][31][32][33][34][35][36][37][38][39], many researchers have systematically investigated the properties of SRR, such as the size and the shape of the SRRs, the size of the unit cell, dielectric properties of the substrate, complementary structures of SRR, and the orientation relative to incident waves in the microwave region.…”

“…The concept of a gap-capacitive LC circuit model makes it possible to estimate the fundamental resonances of the SRRs; nevertheless, additional multiple plasmonic resonances of SRRs [35,[44][45][46][47] were also numerically and experimentally observed recently, an outcome that cannot be interpreted by reference to the gap-capacitive LC circuit model and that still requires a clear explanation. As a consequence, a general model of standing-wave plasmonic resonances reveals the possibility of interpreting SRRs' multiple responses under orthogonal electric excitations.…”

Enriching the Symmetry of Maxwell Equations through Unprecedented Magnetic Responses of Artificial Metamaterials and Their Revolutionary Applications

Abstract:The major issue regarding magnetic response in nature-"negative values for the permeability μ of material parameters, especially in terahertz or optical region" makes the electromagnetic properties of natural materials asymmetric. Recently, research in metamaterials has grown in significance because these artificial materials can demonstrate special and, indeed, extraordinary electromagnetic phenomena such as the inverse of Snell's law and novel applications. A critical topic in metamaterials is the artificial negative magnetic response, which can be designed in the higher frequency regime (from microwave to optical range). Artificial magnetism illustrates new physics and new applications, which have been demonstrated over the past few years. In this review, we present recent developments in research on artificial magnetic metamaterials including split-ring resonator structures, sandwich structures, and high permittivity-based dielectric composites. Engineering applications such as invisibility cloaking, negative refractive index medium, and slowing light fall into this category. We also discuss the possibility that metamaterials can be suitable for realizing new and exotic electromagnetic properties. OPEN ACCESSSymmetry 2011, 3 284

“…The dimension of the sensing device and its radiation property are described in Section 2, and the simulation approach and results to show the strongest E-field in the sensing area are presented in Section 3. Split ring resonators (SRR) have been investigated extensively as a potential metamaterial structure with a negative refractive index [8][9][10][11]. An SRR structure with strong resonance at the THz frequency range is used as a sample material to show the effectiveness of this proposed THz sensor in Section 4.…”

Abstract-A sensing device comprising of a parabolic reflective surface and a bi-conical metal structure is proposed to focus terahertz energy on sample material in the sensing zone to create a strong interaction between terahertz signals and the sample under test. The signal enhancement by the sensing device is confirmed by modeling and simulation results. The proposed sensor is applied to investigate the polarization dependency of a split ring resonator (SRR), and spectral signatures of the SRR under different incident wave polarizations are obtained.
