Compact linear lead/lag metamaterial phase shifters for broadband applications
(2003)A compact one-dimensional phase shifter is proposed using alternating sections of negative refractive index (NRI) metamaterials and printed transmission lines (TL). The NRI metamaterial sections consist of lumped element ...

Compact, linear, lead/lag phase shifters using negative refractive index metamaterials
(2003)A new type of phase shifter using cascaded sections of NRI metamaterials and PRI transmission lines is proposed, which offers some significant advantages over conventional delay lines. The phase shifter is compact in size, ...

Negative-refractive-index transmission-line metamaterials and enabling electromagnetic applications
(2004)The negative-refractive-index (NRI) metamaterials, for which the permittivity and permeability are simultaneously negative, were discussed. The results for two RF/Microwave devices and structures, based on transmission-line ...

Selected antenna applications of Negative-Refractive-Index Transmission-Line (NRI-TL) metamaterials
(2006)Metamaterials (MM) that exhibit a simultaneously negative electric permittivity E and magnetic permeability μ, and thus a negative refractive index (NRI), have recently attracted considerable attention in the electromagnetics ...

Symmetry of differential optical responses of normal and superconducting phases in single-crystal YBCO
(1995)We measured differential optical reflectivity (DOR) of YBCO single domains. DOR measurements reject the temperature independent bulk reflectivity and reveal dR dT. These measurements detect the superconducting transition, ...
