(2005)A 3-port device that converts a single-ended input to a differential output over a large bandwidth is presented. The balun comprises a Wilkinson divider, followed by a +90° negative-refractive-index (NRI) metamaterial (MM) ...
(2005)A metamaterial 1:4 series power divider that provides equal power split to all four output ports over a large bandwidth is presented, which can be extended to an arbitrary number of output ports. The divider comprises four ...
(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 ...
