“…One of the great advantages of metamaterials is that the interaction between EM waves and substances can be successfully tailored by artificially designing or revising unit cells, which provides a great possibility for sensing applications of metamaterials [ 7 , 8 , 9 ]. In fact, with continuous progress in the design and fabrication of metamaterials, the interdisciplinary area between metamaterials and sensing technology has become a fertile ground for the development of new science and technology [ 10 , 11 , 12 , 13 ]. Currently, significant advancements have been made on metamaterial-based sensors, with a level of performance that is able to detect substance information, and interesting and useful sensing applications have been demonstrated for such applications as chemical, food, and biosensing devices [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ].…”

In this work, we propose a metamaterial absorber at microwave frequencies with significant sensitivity and non-destructive sensing capability for grain samples. This absorber is composed of cross-resonators periodically arranged on an ultrathin substrate, a sensing layer filled with grain samples, and a metal ground. The cross-resonator array is fabricated using the printed circuit board process on an FR-4 board. The performance of the proposed metamaterial is demonstrated with both full-wave simulation and measurement results, and the working mechanism is revealed through multi-reflection interference theory. It can serve as a non-contact sensor for food quality control such as adulteration, variety, etc. by detecting shifts in the resonant frequencies. As a direct application, it is shown that the resonant frequency displays a significant blue shift from 7.11 GHz to 7.52 GHz when the mass fraction of stale rice in the mixture of fresh and stale rice is changed from 0% to 100%. In addition, the absorber shows a distinct difference in the resonant absorption frequency for different varieties of grain, which also makes it a candidate for a grain classification sensor. The presented scheme could open up opportunities for microwave metamaterial absorbers to be applied as efficient sensors in the non-destructive evaluation of agricultural and food product quality.

“…The main property of such sensors is that they have extremely small size (much less than wavelength/2) and large Q factor, thereby showing high sensitivity to the parameter which is to be sensed. Various applications have already been realized such as sensing of solid dielectrics [71], liquids [72], hybrid fuels, hazardous chemicals [66,73,74], gas [75,76], and biomolecules [77,78]. Therefore, this new category of sensors is here to stay for the coming few decades and needs proper further evaluation to replace existing sensors.…”

In recent times, the global science and technology is dominated by research in the nanotechnology domain, especially to explore novel materials with exotic properties, which are attributed to their nano-size regimes. Typically explored examples are metals (gold, silver, copper, etc.), organic and inorganic materials (metal oxides, polymers), carbon (graphene, CNTs, etc.), and so on, typically, in their pure and composites forms. The polymers are playing a vital role in this domain, to make the polymer-based nanocomposites, which are used for different

“…CSRR structures have also been extensively used for sensing applications mostly in the microwave range (Boybay and Ramahi, 2012) , (Ebrahimi et al, 2014) , (Rawat et al, 2015). These electrical metamaterial (double CSRR) structures for hybrid fuel and high energy materials have been explored, due to their ease of sensing mechanism and high sensitivity (Rawat et al, 2014) , (Rawat et al, 2015) , (Rawat et al, 2016). Apart from these, a lot of variants of SRRs have been designed and fabricated such as spiral resonators, broadside coupled split-ring resonator (BC-SRR), two-layer multi spiral resonator (TL-MSR), the broad-side coupled spiral resonator with four turns, the open split-ring resonator (OSRR), and the open complementary split-ring resonator (OCSRR)(Duran-Sindreu et al, 2011).…”

“…These materials are apt for sensing applications as they offer high miniaturization and large values of Qfactor which makes them highly sensitive to environmental changes. Such properties of metamaterials also suggest their suitability for material sensing which include solid dielectrics (Boybay and Ramahi, 2012), liquids (Ebrahimi et al, 2014), hybrid fuels, hazardous chemicals , (Rawat et al, 2014) , (Rawat et al, 2015) , (Rawat et al, 2016), gas sensing (Zarifi et al, 2016) (Kaushik et al, 2015)and biomolecules (Lee et al, 2012) , (Clark et al, 2009). Metamaterial-based sensors in general have given a new headway towards novel systems for sensing.…”

Potential applications of thin film metamaterials are diverse and their realization to offer miniaturized waveguides, antennas and shielding patterns are on anvil. These artificially engineered structures can produce astonishing electromagnetic responses because of their constituents being engineered at much smaller dimensions than the wavelength of the incident electromagnetic wave, hence behaving as artificial materials. Such micro-nano dimensions of thin film metamaterial structures can be customized for various applications due to their exclusive responses to not only electromagnetic, but also to acoustic and thermal waves that surpass the natural materials' properties. In this paper, the recent major advancements in the emerging fields of diagnostics (sensors) and therapeutics involving thin film metamaterials have been reviewed and underlined; discussing their edge over conventional counterpart techniques; concentrating on their design considerations and feasible ways of achieving them. Challenges faced in sensitivity, precision, accuracy and factors that interfere with the degree of performance of the sensors are also dealt with, herein.
