Periodic analysis of a 2-D negative refractive index transmission line structure (2003, result): “Furthermore, a 1-D fast-wave implementation of this metamaterial was shown to exhibit backward-wave radiation from its fundamental spatial harmonic, an effect similar to what Veselago [5] termed “reversed Cherenkov radiation” [8], [9].”
Equivalent-circuit models for split-ring resonators and complementary split-ring resonators coupled to planar transmission lines (2005, background): “Following this seminal paper, other artificially fabricated structures exhibiting a left-handed behavior were reported [8]–[11] including the experimental demonstration of negative refraction [12]–[14] and backward wave radiation [15].”
A positive future for double-negative metamaterials (2005, background): “…(e.g., [8], [54]–[59]), sub-wavelength waveguides with lateral dimension below diffraction limits (e.g., [26], [27], [60]–[63]) enhanced focusing (see [46] and [64]), backward wave antennas [44], ˇ Cerenkov radiation [65], photon tunneling [66], [67], and enhanced electrically small antennas [68].”
Overcoming the diffraction limit with a planar left-handed transmission-line lens. (2004, background): “Moreover, at higher frequencies where discrete elements are not readily available, it would be more advantageous to construct the lenses based on entirely printed-circuit methods as it is documented in [3] and [ 4 ].”
Metamaterial-based electronically controlled transmission-line structure as a novel leaky-wave antenna with tunable radiation angle and beamwidth (2004, background): “Recently, a metamaterial-based backward radiating leaky-wave (LW) antenna was presented in [13] and [14].”
Planar distributed structures with negative refractive index (2004, background): “mensional (1-D) TL implementations with practical applications such as backward-to-forward leaky-wave antennas [8], [ 9 ], tight/dual-band couplers [10], and zeroth-order resonators [11] using microstrip lines or coplanar waveguides (CPWs).”
High-gain active composite right/left-handed leaky-wave antenna (2006, background): “This concept matured quickly and led to the first backfire-to-endfire CRLH LWA [6], after LH backward wave radiation was demonstrated in [7], [8].”
Compact linear lead/lag metamaterial phase shifters for broadband applications (2003, methodology): “It can be observed that the corresponding dispersion diagram exhibits a band structure with two distinct passbands and stopbands as in [5] and [7].”
Transmission line models for negative refractive index media and associated implementations without excess resonators (2003, background): “Implementing this idea based on printed transmission-line networks, compact, fully planar, broadband negative refractive index media have been proposed [7], [8].”
CRLH metamaterial leaky-wave and resonant antennas (2008, background): “It should be noted that backward radiation using a onedimensional left-handed transmission line (first demonstrated in [4]) was verified before [13] in [14].”
