Design Method for Negative Group Delay Circuits Based on Relations among Signal Attenuation, Group Delay, and Bandwidth [PDF]
Journal of the Korean Institute of Electromagnetic Engineering and Science, 2019 Typical negative group delay circuits (NGDC) are analyzed in terms of signal attenuation, group delay, and bandwidth using S-parameters. By inverting these formulations, we derive and present the design equations (for NGD circuit elements) for a desired ...

Frequency-Selective Surface Based on Negative-Group-Delay Bismuth–Mica Medium
Photonics, 2023 Negative group delay may be observed in dispersive media with anomalous dispersion in a certain frequency range. The fact that an outgoing wave packet precedes an incoming one does not violate the causality principle but is only a consequence of a ...

Negative group delay synthesiser
Electronics Letters, 1993 A network that synthesises negative group delay is presented. The conditions required for achieving negative group delay, with a simple R-L-C tuned circuit, are briefly introduced. A hybrid MIC realisation of the network, operating at 1 GHz, is described and its measurements are reported.

A Compact Transmission-Line Self-Matched Negative Group Delay Microwave Circuit
IEEE Access, 2017 A compact self-matched negative group delay (NGD) circuit without the need for an external matching circuit is proposed. The proposed NGD circuit is composed of two-port open-circuited coupled lines, a short-circuited transmission line and two resistors ...
