“…We consider the normal and oblique incidence of transverse electromagnetic waves. To summarize, our proposed structure has a high absorption bandwidth with high angular incidence stability compared to recent works that have been proposed [23,[32][33][34][35]. In addition to the simplest manufacturing process, layer-by-layer deposition with thinthickness structures is also used.…”

A layered structure composed of polyaniline (PANI) and silicon dioxide (SiO2) is proposed in this article. It was developed to obtain ultra-wideband and high-power microwave absorption. Due to the high thermal stability of PANi and SiO2 above 400 °C, the proposed structure is able to absorb high amounts of power. The electromagnetic behavior of the structure is examined by full-wave simulation to investigate its ability to absorb microwave frequencies ranging from 1 to 20 GHz under both normal and oblique incidences of electromagnetic waves. Recent studies have produced results with a limited absorption range and a less consistent angular incidence than the structure presently being examined. Also, the layer-by-layer deposition of thin film facilitates the manufacturing procedure. Furthermore, owing to the high thermal stability of the proposed structure, the absorption of high-power microwaves is superior to that of alternative methodologies.

“…The concept of a perfect metamaterial absorber started in the early work of Landy et al in 2008 who succeeded in making a single narrowband near-perfect absorber in a microwave band. Since this date, many designs have appeared that have perfect absorption with a single narrow band, multi-narrow band, and wideband spectrum in microwave, terahertz, infrared, and visible spectral bands (Ye et al 2010;Bai et al 2015;Lv et al 2015;Liu et al 2020;Cai et al 2020;Chen et al 2022;Abouelez and Abdulaleem 2023;Zolfaghary pour and Arik 2023;Errajraji et al 2024).…”

Ultra-broadband metamaterial absorbers (UBMA) that are compatible with CMOS technology for use in the mid-infrared (mid-IR) and long-wave infrared (LWIR) regions are crucial for a variety of applications, including radiative cooling, thermal photovoltaic, and thermal imaging. In this regard, we propose, in this work, a design of a UBMA based on the heavily doped silicon (D-Si) and silicon carbide (SiC). The 3D finite-difference time-domain method is used to numerically calculate the optical characteristics of the proposed UBMA. The absorber, which is made up of a periodic array of symmetrical multilayered square rings of D-Si and SiC, achieves high absorption with an average absorption of 95% over a wavelength range of 2.5 µm to 22 µm. This broad range of wavelength absorption is attained, encompassing the mid-, long-wave, and partial far-infrared regions. In addition to the materials' inherent absorption, the stimulation of magnetic polaritons, surface plasmon polaritons, localized surface plasmon resonance, and cavity resonance are responsible for the nearly perfect broadband absorption. The proposed UBMA is polarization-independent due to the symmetrical design of the absorber. Furthermore, the impact of the incidence angle on the absorption of transverse electric-polarized and transverse magnetic waves is examined.

The concept, performance, and analyses of distinctive, miniaturized metamaterial (MTM) unit cell addressing the forthcoming Sub 6 GHz 5G applications are presented in this paper. Two circular split-ring resonators (CSRR) with two parallel rectangular copper elements in front of the design and a slotted square element in the background make up the suggested metamaterial. It has a line segment with tunable features that is positioned in the center of the little ring copper structure. The suggested design offers a significant operating frequency band of 220 MHz together with a resonance of transmission coefficient S21 at 3.5 GHz. Furthermore, in two (z & x) principal axes of wave propagation, wide-range achievement, single/double-negative (S/DNG) refractive index, negative permittivity, and near-zero permeability properties were demonstrated. Through varying central slotted-strip line length, resonance frequencies can be selectively altered. Moreover, the metamaterial has overall dimensions of 9 × 9 mm2 and is composed on a Rogers 5880 RT substrate. In order to create the suggested MTM's equivalent circuit, which shows similar coefficient of transmission (S21), a proposed design’s numerical simulation is carried out in the CST micro-wave studio. This simulation is after that put to comparison with manufacturing of the design.
