“…Metamaterials(MMs) [1,2] are artificial effective electromagnetic structures with subwavelength scale cells. It obtains the properties which cannot be found in nature, such as negative refraction index [3], cloaks [4], superlens [5] and extraordinary optical transmission [6]. Metamaterial perfect absorbers(MPA) have been proposed at microwave by Landy et al in 2008 [7].…”

“…Metamaterial perfect absorbers(MPA) have been proposed at microwave by Landy et al in 2008 [7]. MPA can be applied in many fields, such as solar energy [8,9], plasmonic sensors [10], bolometers and photo-detectors [3]. During the last years, many kinds of metamaterial absorbers have been extensively investigated: the stair-like 3D structure [11], multi-metallic-layers structure [12], flexible and lightweight substrate [13,14], planner structure [15], transparently curved metamaterial [6] and so on.…”

In this paper, the absorbing property of metal-cross shaped metamaterial dihedral (MCMD) and cross-cross shaped metamaterial dihedral (CCMD) with the same parameters are investigated. In TE mode, the absorptivities are 91.1% at 9.17 GHz for MCMD and 99.7% at 9.20 GHz for CCMD. For MCMD and CCMD, the absorptivities are 90.5% and 99.8% at 9.2 and 9.17 GHz respectively for the TM polarized incident wave. The results of simulation and measurement show that CCMD has better multi-band absorption performance and lower radar cross-section than MCMD. Experiments have demonstrated the reflection coefficient can be utilized to analyze the electromagnetic characteristics of dihedral corner as well. The study of dihedral corner reflector is of great importance as it is used in modeling many areas such as stealth technology, electromagnetic compatibility and target recognition.

“…Other researchers [11,12,13,14] have studied how the edge effect increases the measured absorption in a reverberation chamber due to the extra surface area that is present because of the thickness of the sample under test. Ye t other studies concentrate on absorbers based on the passive destructive interference principle (PDI) [15] or based on metamaterials [16,17]. However, none of these studies has found a simple method that allows to predict the improvement produced in the sound absorption of a dwelling, using a given amount of absorbent material but placing it in separated pieces.…”

The sound absorption coefficient of three different materials is proved in a reverberation room against different layouts of the material and different back air layers, compared to those results where the same material is placed as a single piece. With the analysis of the data, a linear regression model is established in order to predict, for certain frequencies, the alteration produced in the absorption coefficient by using the same amount of material but placing it in patches separated from each other, instead of in one piece, and at different distances from the wall. The model is validated and proven to be robust and it is shown to be applicable to a variety of materials. It becomes a simple predictive tool which allows to estimate in situ the improvement in the absorption property of an absorbent material due to the separation of the patches.

This paper proposes a wideband and polarization-insensitive metamaterial absorber (MA) based on tractable conductive plastic, which is compatible with an additive manufacturing technology. We provide the design, fabrication, and measurement result of the proposed absorber and investigate its absorption principle. The performance characteristics of the structure are demonstrated numerically and experimentally. The simulation results indicate that the absorption of this absorber is greater than 90% in the frequency range of 16.3–54.3 GHz, corresponding to the relative absorption bandwidth of 108%, where a high absorption rate is achieved. Most importantly, this additive manufactured structure provides a new way for the design and fabrication of wideband MAs.
