Metamaterial-based electronically controlled transmission-line structure as a novel leaky-wave antenna with tunable radiation angle and beamwidth (2004, background): “[7] and Iyer and Eleftheriades [8] proposed a transmission line (TL) approach for LH metamaterials.”
Transmission line approach of left-handed (LH) materials and microstrip implementation of an artificial LH transmission line (2004, methodology): “face with a 2-D transmission line were demonstrated in [27] in a lumped-element structure and in [28] in a distributed structure.”
A compact enhanced-bandwidth hybrid ring using an artificial lumped-element left-handed transmission-line section (2004, background): “However, the first approaches of LH materials were mainly based on an analogy with plasmas, which naturally resulted in resonant-type structures not suitable for practical microwave applications because of their excessive loss and narrow bandwidth [2], [3].”
Transmission line models for negative refractive index media and associated implementations without excess resonators (2003, background): “However, what is striking here is that 2-D versions of such periodically loaded transmission line media lend themselves as practical left-handed media that are capable of demonstrating reversed refraction and focusing when interfaced with conventional right-handed media such as a parallel-plate wave”
A compact and low-profile metamaterial ring antenna with vertical polarization (2005, methodology): “A two-dimensional loaded transmission line (TL) metamaterial (MM) was developed that exhibits negative-refractiveindex (NRI) properties [2], [3].”
A novel composite right-/left-handed coupled-line directional coupler with arbitrary coupling level and broad bandwidth (2004, background): “Recently, an extended transmission-line (TL) approach of LH materials, using nonresonant and, therefore, low-loss and broad-bandwidth structures, was proposed almost simultaneously by three different groups [15]–[17].”
Dual-Band Impedance-Matching Networks Based on Split-Ring Resonators for Applications in RF Identification (RFID) (2010, background): “capacitors and shunt inductors [1]–[3] and 2) the resonant type”
CRLH metamaterial leaky-wave and resonant antennas (2008, background): “The latter approach, introduced in [ 4-6 ], has led to low-loss and broadband metamnaterials, due to the non-resonant nature of the structural elements.”
A broadband Wilkinson balun using microstrip metamaterial lines (2005, methodology): “More recently, a planar NRI medium was realized by periodically loading a conventional transmission line (TL) with lumped-element series capacitors ( ) and shunt inductors ( ) in a dual-TL (high-pass) configuration [3]–[5].”
Arbitrary dual-band components using composite right/left-handed transmission lines (2004, positive): “RECENTLY, left-handed (LH) materials have gained significant attention in the microwave community [1]–[4].”
Compact linear lead/lag metamaterial phase shifters for broadband applications (2003, background): “More recently, a compact two-dimensional dual transmission line (TL) network was developed that exhibits simultaneous negative and , and has been shown to experimentally demonstrate negative refraction and focusing of guided waves [3], [5].”
Planar negative refractive index media using periodically L-C loaded transmission lines (2002, methodology): “In [11], a procedure was described for the design of high-pass – networks to demonstrate negative refraction.”
Periodic analysis of a 2-D negative refractive index transmission line structure (2003, methodology): “A 1-D theory of operation for the NRI TL metamaterial was presented in [6]–[10] which considered propagation solely along the structure’s principal axes.”
