“…[4] These materials have many unconventional properties that cannot be found in nature such as negative reflective index, negative permeability, negative refraction and so on. [6][7][8][9][10][11] Super lens, [11,12] cloaking, [11,13,14] electromagnetic filters, [15,16] high frequency polarization rotators [11,17] and absorbers [4][5][6]11] are some of the application areas of metamaterials. Recently metamaterials as an absorber have gained attention and there are many studies have been made in the literature [18][19][20][21][22][23][24][25][26][27][28].…”

A new perfect metamaterial absorber based on metal-dielectric layer combination is designed and investigated to be used in solar cell application. The designed structure is particularly presented in the range of solar spectrum in order to utilize the solar energy effectively. Parametric studies with respect to the dimensions of the structure are carried out to characterize the absorber. According to the results, it is found that the metamaterial absorber has 99.99% absorption at 403.5 THz. In addition, the fractional bandwidth (FBW) of the absorption region is calculated and 22.2% FBW is obtained. Moreover the simulation results showed that the proposed design is also polarization and incident angle insensitive. As a result, the proposed metamaterial absorber provides perfect absorption for visible and near infrared frequency ranges and can be used for the realization of more efficient new solar cells.

“…As a new type of artificial materials, it can be applied to many disciplines, such as filter, waveguide, resonator and antenna [6][7][8][9]. To date, MMs have been demonstrated in every spectral range, from radio [10], microwave [4], mm-wave [11], THz [12], MIR [13], NIR [14], and even near optical [15]. Most of the MMs are made of periodically arranged metallic structures much smaller than the working wavelength in size.…”

“…The initial impetus driving metamaterial research was the realization of effective negative permittivity, permeability and refractive index [1][2][3][4]. Since the experimental demonstration of negative refractive index in the left-handed metamaterials (LHMs) by Smith [5], MMs research has attracted intense attention of the scientific community.…”

Abstract-In this paper, we present the design, simulation, and measurement of a dual-band metamaterial absorber in the microwave region. Simulated and experimental results show that the absorber has two perfect absorption points near 11.15 GHz and 16.01 GHz. Absorptions under different polarizations of incident EM waves are measured with magnitude of over 97% at low-frequency peak and 99% at high-frequency peak respectively. Current distribution at the dual absorptive peaks is also given to study the physical mechanism of power loss. Moreover, it is verified by experiment that the absorptions of this kind of metamaterial absorber remain over 90% at the low-frequency peak and 92% at the high-frequency peak with wide incident angles ranging from 0 • to 60 • for both transverse electric wave and transverse magnetic wave.

“…Metamaterials are artificial effectively homogeneous electromagnetic structures composed of metals and dielectrics. The initial impetus driving meta-material research was the realization of effective negative permittivity, permeability and refractive index [8][9][10]. The radar absorbing material structure with a mushroom-like HIS and a chip resistor is proposed [11,12].…”

-This paper proposes a novel design for a compact, high-isolation WCDMA indoor repeater antenna. The proposed antenna consists of a patch antenna and metamaterial absorber. The required WCDMA bandwidth is obtained by utilizing the coupling between the main and the parasitic patches. In addition, high isolation is achieved using the metamaterial absorber, which has an absorption of about 98% at 2.1 GHz. Overall, the proposed antenna has a gain of over 7 dBi, a Voltage Standing Wave Ratio (VSWR) of less than 2, more than 85 dB of isolation between the service and donor antennas over the WCDMA band and a total volume of the proposed antenna only 70 mm × 70 mm × 43.8 mm.
