“…Since the groundbreaking work of Landy et al [1] on perfect metamaterial absorbers (PMMA), this concept has gained significant attention in the field of science and technology. PMMAs have been extensively developed across various electromagnetic (EM) spectrum ranges, including microwave [1,2,3], terahertz [4,5,6,7,8,9,10,11], infrared [12,13,14,15,16], and visible regions [17,18,19,20]. The advantage of PMMA lies in its geometric scalability, allowing it to operate at different EM spectrum ranges without being limited by the quarter-wavelength thickness.…”

“…High-order resonances of metamaterials (MMs) are often overlooked in PMMA designs, but they can play a crucial role in achieving multi-band absorption. Several studies have demonstrated the combination of fundamental and high-order resonance modes in a single patterned metallic structure [3,8,11,34,35,36,37], resulting in multi-band absorption.…”

We have developed and simulated a planar complementary Archimedes-based metamaterial absorber with the goal of its application in refractive index sensing. Unlike designs that employ multiple layers or numerous resonators within a single unit cell, our proposed absorber adopts a more streamlined approach. It consists of three layers, with an FR4 dielectric substrate sandwiched between two copper layers. It's important to note that the absorption characteristics of this design are polarization-dependent. This polarization dependence arises from the asymmetrical resonance behavior observed in both the x and y directions. The absorber exhibits impressive absorption rates at various resonance frequencies, namely 98.5% at f1 = 8.49 GHz, 77.1% at f2 = 8.88 GHz, 88.7% at f3 = 9.3 GHz, 98.2% at f4 = 9.87 GHz, 99.7% at f5 = 10.65 GHz, 83.4% at f6 = 11.58 GHz, and 99.9% at f7 = 12.24 GHz. Furthermore, we've explored the refractive index sensing capabilities of this structure by introducing a 1 mm analyte layer on top of the patch structure. Through refractive index sensing analysis, we've determined that this absorber-based sensor yields an impressive high-quality factor value of 84.5, underscoring its sensitivity and precision. To gain a deeper understanding of the physical mechanisms at play, we've conducted an analysis of surface current distribution plots. Additionally, we've investigated the behavior of the absorber under varying polarization and incident angle conditions, ranging from zero degrees to sixty degrees. This comprehensive characterization positions our absorber as a promising candidate for microwave sensing applications.

“…Researchers have reported various forms of PMAs suitable for operation in microwave, terahertz, visible and ultraviolet regions [ [22] , [23] , [24] ]. The desired absorption band is achieved by optimising the geometric parameters of the constituent meta-atoms, which are the building blocks of the metamaterial structure.…”

“…MTMs not found in nature, which are expressed as man-made structures that can be artificial or synthetic, have many research areas such as MTM absorber (MMA) (Landy et al, 2008;Wang et al, 2017;Xie et al, 2018;Al-Badri, 2021), sensors (Yang et al, 2013;Zhao et al, 2015;Akgol et al, 2017;Altintas et al, 2017), harvesting (Ramahi et al, 2012;Karaaslan et al, 2017;Bakır, 2018), MTM based antennas (Afridi et al, 2013;Tetik et al, 2018), and terahertz (THz) (Ling et al, 2018;Tetik, 2020;Han et al, 2021) applications. MTMs can suppress EM wave propagation in a certain frequency band which exhibits exceptional EM characteristics such as cloaking, backward propagation, and negative refraction.…”

The development of technology implies the release of several gases to the environment. These gases, especially toxic ones, have many negative effects on human life and cause many diseases that will adversely affect human health. In this respect, effective and accurate identification of these gases are important in terms of preventing possible damages. In this study, a sensor design that can detect toxic gases using a metamaterial structure operating in the gigahertz frequency range is presented. Metamaterials not found in nature are defined as artificial or synthetic structures and can be used in many applications, including sensors, thanks to their negative index of refraction. Here a metamaterial-based sensor application for the detection of the carbon monoxide, a toxic gas, is investigated. The sensor performance was analyzed by adding 50% and 100% toxic gas to the suggested metamaterial design, and 0.010 and 0.013 THz shifts were obtained in the resonance frequency, respectively. This shift indicates that this structure is a viable candidate in sensor applications for the carbon monoxide.
