“…Recent studies show that MTMs provide improvement in light collection for solar cells [5][6][7]. MTMs are artificial structures [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] and they can be specifically constructed for many desired physical properties and applications which cannot be obtained from the conventional materials such as negative refractive index [24], cloaking [25], super lens [26], absorber [27], and so on. Therefore, MTMs have gained a great deal of interest due to their large applicability in the development of efficient devices.…”

Abstract-We design, characterize, and analyze a new kind of metamaterial (MTM) absorber (MA) in different frequency regions for the solar cell applications. This MTM based structure is particularly presented in a range of the solar spectrum in order to utilize the solar energy effectively. The proposed MTM based solar cell provides perfect absorption for both infrared and visible frequency ranges and can be used for the realization of more efficient new solar cells. The structure is also tested in terms of the polarization angle independency. The suggested MA has a simple configuration which introduces flexibility to adjust its MTM properties to be used in solar cells and can easily be re-scaled for other frequency ranges. Our experimental results in microwave frequencies confirm the perfect absorption for the resonance frequency and agree with the simulation results. This means that the developed MA for solar cells will offer perfect absorption in infrared and even in visible frequencies.

“…Negative index metamaterials (NIMs) have attracted great attention due to their fascinating electromagnetic (EM) properties such as perfect lens, near-field imagings, cloakings, reversal of the Doppler effects, and so on [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. A well-established route of constructing NIM structures is based on the Veselago's theory of left-handed materials (LHM), simultaneous negative permittivity and permeability [16].…”

Abstract-We propose an effective way to realize the ultra-low loss in a split ring resonator (SRR) by suppressing the electric dipole moment approach. To tremendously reduce the loss, the loss mechanism of the SRR is theoretically analyzed in detail. The nonuniform current distribution on the SRR loop results in the residual electric dipole moment and thus brings the high radiation losses. Three different SRR configurations that the lumped capacitor, the distributed capacitor and the dielectric medium are incorporated into the SRR metamaterial are conceived, by which the uniform current distribution can be observed. This leads to in a finite bandwidth deviated from the resonance frequency where the SRR's loss performance dramatically improves owing to suppression of the residual electric dipole moment. The proposed the loss reduction mechanism has potential applications in negative and zero index metamaterials, especially at THz frequencies and in the optical regime.

“…The metamaterials are designed on circuit board so it may be easily integrated into the cellular phone. Simulation of wave propagation into metamaterials was proposed in [23][24][25]. This method is a helpful approach to study the wave propagation characteristics of metamaterials [26][27] and has been developed more with the perfectly matched layer (PML) and extended to the three-dimension problem [27].…”

The purpose of this paper is to calculate the reduction of specific absorption rate (SAR) with a new design of square metamaterials (SMMs). The finite-difference time-domain (FDTD) method with lossy-Drude model is adopted in this analysis. The method of SAR reduction is discussed and the effects of location, distance, and size of metamaterials are analyzed. SMMs have achieved a 53.06% reduction of the initial SAR value for the case of 10 gm SAR. These results put forward a guideline to select various types of metamaterials with the maximum SAR reducing effect for a cellular phone.
