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 ...

A CPS leaky-wave antenna with reduced beam squinting using NRI-TL metamaterials
(2008)A reduced beam-squinting printed leaky-wave antenna (LWA) is proposed, comprising cascaded negative-refractive-index transmission-line (NRI-TL) metamaterial unit cells. Each NRI-TL unit cell is implemented in co-planar ...

Permeability calculations in three-dimensional isotropic and oriented fiber networks
(2008)Hydraulic permeabilities of fiber networks are of interest for many applications and have been studied extensively. There is little work, however, on permeability calculations in three-dimensional random networks. Computational ...
