Anomalous negative group velocity (NGV; group velocity antiparallel to the power flow) is
reported in a guided-wave structure supporting complex modes. This structure consists of a …

An analogy is demonstrated between negative group delay (NGD) networks and non-Foster
reactive elements. It is shown that non-Foster elements and NGD networks influence a …

A dual–band printed metamaterial coupler made of a microstrip line and a generalised
negative-refractive-index (NRI) line is presented. Owing to the presence of two left-handed …

The microstrip/negative-refractive-index transmission-line (MS/NRI-TL) coupler is
constructed by edge coupling a regular microstrip line to a backward wave negative …

This PhD dissertation explores novel electromagnetic applications using negative-group-
delay (NGD) and non-Foster structures and establishes an intimate connection between …

Many researchers have introduced various metamaterial structures such as spiral resonator,
split ring resonator, complementary split ring resonators, omega, S structures etc., in recent …

A dual-band printed metamaterial coupler made of a microstrip line and a generalized
negative-refractive index line is presented. Due to the presence of two left-handed bands in …

This article presents an overview of the generalized negative‐refractive‐index transmission‐
line (G‐NRI‐TL) and summarizes the design equations that determine the frequencies of …

This thesis proposes a novel approach to dispersion extraction of an N-stage composite
right-handed/left-handed transmission line (CRLH TL) using near-field scanning S …
