“…It has been reported that MW sensors based on MTM TLs can achieve significantly higher sensitivity levels than sensors based on conventional TL (more than 10 times higher) [7,[20][21][22]. In these studies, the interaction is very dependent on the chosen unit cell and especially on how the unit cell is implemented.…”

“…These permittivity sensors are aimed at many topics, including material characterization [3]- [5] (this is indeed the context of the sensors proposed in this work), analysis of organic tissue [6] [7], microfluidics [8]- [11], biosensing [12]- [16], or environmental factors [17]. Other planar permittivity sensors implemented by means of artificial transmission-lines have also been proposed [18]- [20].…”

Differential techniques are widely used in communication and sensor systems, as these techniques have been shown to improve the performance. This paper shows how differential sensing of permittivity can be conducted in a simple way. For that purpose, a microstrip line loaded with a pair of stepped impedance resonators is used in two different resonator connections: parallel and cascade. Each resonator is individually perturbed dielectrically so that: (i) when the two individual permittivities are identical, the structure exhibits a single resonance frequency; (ii) when the permittivies are different, resonance frequency splitting occurs, giving rise to two resonances (all these resonances are seen in the form of transmission zeros). The two sensing approaches are successfully validated through electromagnetic simulations and experiments. By virtue of a differential measurement, robustness against changing ambient factors that may produce sensor miscalibration is expected.

“…Many of them are based on the split ring resonator (SRR) [24,[151][152][153][154][155][156][157][158][159], and many others on the CRLH transmission line [160][161][162][163][164][165][166][167][168][169][170][171][172][173][174], mainly reported by the Group of Professor R. Jakoby at Darmstadt (Germany).…”

This paper is focused on the application of concepts derived from metamaterials to the development of novel devices, circuits, and antennas of interest in wireless communications, radiofrequency identification (RFID), and sensors. Specifically, it is shown that artificial transmission lines based (or inspired) on metamaterials exhibit interesting properties, useful for the implementation of high-performance and compact devices as well as novel functional devices. Thanks to the presence of reactive loading elements in such artificial lines, the main line parameters, that is, the characteristic impedance and the phase constant, can be engineered. This has opened new paths for RF and microwave circuit and antenna design on the basis of impedance and dispersion engineering.
