Design and Simulation of Metamaterial Sensor and Numerical Formulation for Dielectric Properties

Metal Discovery by Highly Sensitive Microwave Multi-Band Metamaterial-Inspired Sensors

“…In the next section, we present our metamaterial (MTM) and its electromagnetic properties, followed by an MTM array integration with the bowtie to investigate the enhancement of metal detecting sensitivity. [23,35,50] and rectangular [32,34,36,49,55,56] shapes, the most common MTM structures, are combined with a quarter wavelength transmission line or a simple antenna to design a compact electromagnetic contactless sensor. These SRR structures can be optimized as a separate [23,48,57,59,60] or concentric [35,36,49,50,55,56] SRR array, derived from a conventional SRR.…”

Other MTM shapes like H-shape [37,51], X shape [43], omega shape [47], and U shape [45] are also found in some specific MTM-inspired sensors.…”

“…MTM-inspired sensors then can be designed to operate in a single band [36, 37, 41-43, 46-49, 51] or multibands [23,33,34,[59][60][61] with higher sensitivity. MTM-inspired sensors have been employed for a variety of detecting purposes, for instance, liquidor fluid [23-25, 34, 43, 44, 46-48, 53-55, 57, 63, 65-69, 95], solid dielectric material [35,36,38,52,58,62,70], or biomaterials [37,49,50,80,91].…”
