Journal ArticleDOI
Planar negative refractive index media using periodically L-C loaded transmission lines
TL;DR: In this article, the authors proposed an alternate perspective on the design and function of such materials that exploits the well-known L-C distributed network representation of homogeneous dielectrics.
Proceedings ArticleDOI
Negative refractive index metamaterials supporting 2-D waves
TL;DR: In this article, it was shown that planar, two-dimensional L-C transmission line networks in a high pass configuration can demonstrate negative refraction as a consequence of the fact that such media support propagating backward waves.
Journal ArticleDOI
Transmission line models for negative refractive index media and associated implementations without excess resonators
TL;DR: In this article, the authors propose transmission line models for studying and interpreting the electromagnetic propagation behavior of composite periodic media, and show that by periodically loading a network of transmission lines with series capacitors and shunt inductors, a negative refractive index medium can be synthesized without excess resonators, thus leading to wideband behavior.
Journal ArticleDOI
Strongly Enhanced Sensitivity in Planar Microwave Sensors Based on Metamaterial Coupling
TL;DR: In this paper, a negative-refractive-index TL MTM-infused planar microwave sensor is designed for operation at 2.5 GHz and is shown to exhibit a significant improvement in sensitivity and linearity.
Journal ArticleDOI
Strongly Enhanced Sensitivity in Planar Microwave Sensors Based on Metamaterial coupling
TL;DR: In this paper, a negative-refractive-index TL (NRI-TL) was used to improve the sensitivity and linearity of planar microwave sensors. But the resulting sensitivity and sensing range are ultimately limited by the level of coupling between the OLR and the TL.
