“…[ 92 , 93 ] One group utilized four orthogonal SRRs, similar to the design mentioned above [ 100 ] giving them a bandwidth of 42%. [ 93 ] In order to overcome this challenging fabrication problem of how to realistically impedance match at two separate frequencies, another group utilized a genetic algorithm to optimize their design. [ 92 ] In an example of a multistructure MPA, one study scales multiple ELCs in their unit cell to achieve a multi-absorption response; they are able to do this with two and three separately resonating structures.…”

The advent of negative index materials has spawned extensive research into metamaterials over the past decade. Metamaterials are attractive not only for their exotic electromagnetic properties, but also their promise for applications. A particular branch–the metamaterial perfect absorber (MPA)–has garnered interest due to the fact that it can achieve unity absorptivity of electromagnetic waves. Since its first experimental demonstration in 2008, the MPA has progressed significantly with designs shown across the electromagnetic spectrum, from microwave to optical. In this Progress Report we give an overview of the field and discuss a selection of examples and related applications. The ability of the MPA to exhibit extreme performance flexibility will be discussed and the theory underlying their operation and limitations will be established. Insight is given into what we can expect from this rapidly expanding field and future challenges will be addressed.

“…One is the conventional metamaterial absorber called coupled-model, 16 which can directly obtain the absorptivity from simulations or measurements using conventional method. [4][5][6][7][8][9][10][11] Another one is only the metamaterial resonator (the ground plane is removed) called decoupled-model, 16 which need the above equations for getting the absorptivity via the simulated scattering parameters (S-parameters). Such two models are shown in Figs.…”

“…2,3 Most recent works have focused on the realizations of MMA operated at virous frequency spectra ranged from acoustics through microwave and terahertz to optical bands, by using different metamaterial resonators. [4][5][6][7][8][9][10][11] Little attention, 12-16, 21, 22 however, has paid on the discussions of the theories or mechanisms of absorption, which is very important for potential research of MMA. Among these theoretical studies, impedance matching theory presented by Tao et al 12 is a widely acceptable theory for the MMA analysis.…”

Metamaterial absorber (MMA), which is a kind of thin electromagnetic absorber consisting of sub-wavelength metamaterial resonators and can exhibit near-perfect absorption characteristics, has been widely investigated in recently years. The impedance matching theory was proposed to analyze the configuration of MMA in most literatures. Such theory, however, may not suitable to analyze the interactions of metamaterial resonators and the ground plane. The interference theory, on another hand, can play effective approach for this kind of problem presented in recent studies, whereas little attention has been paid on the oblique incidence conditions. In this paper, we firstly extend the interference theory model to make it applicable for oblique incident waves and analyze MMA using the extended interference theory model. Secondly, we further explore the sufficient condition for the maximum absorptivity at both normal and oblique incidence cases. Thirdly, with the sufficient condition, we can obtain the absorbing frequency directly if the thickness of MMA is given. These theoretical results have significant effects on the design and analyze of MMA. And lastly, we point out that absorptivity is not absolutely insensitive to the incidence angle in TM mode as what previous study claims, but insensitive when the dielectric slab is high loss, which can also be explained by interference theory

“…This type of absorber includes a resistive sheet and a metallic ground plane to cancel out reflections from the screen. Recently, the absorber technology has seen several advancements in the use of artificially structured metamaterials (MTMs) for the microwave terahertz, infrared, and optical frequency regimes [2][3][4][5]. Additionally, much works has done in integrating MMAs into creating novel devices applications [6][7][8][9].…”

Abstract-In this paper, we present a new type of a double-negative metamaterial absorber (MMA) with a periodic array composed of in-plane an electric-field-coupled-LC (ELC) resonator and a wire. In contrast to common MMA configurations, a metallic pattern layer of the proposed absorber is placed parallel to the incident wave propagation direction. An appropriately designed combination structure is etched on one side of an FR-4 substrate. Here, we fabricated a prototype absorber with a planar array of 66 × 30 unit cells. Our experiments showed that the proposed absorber exhibited a peak absorption rate greater than 86% at 10.1 GHz irrespective of the incident angles up to 60 • .
