NGD Analysis of Turtle-Shape Microstrip Circuit

IEEE Transactions on Circuits and Systems II: Express Briefs, 2020
A negative group delay (NGD) design of a turtle shape circuit topology is developed in this brief. The topology is comprised of two different length transmission lines (TLs) interconnecting two identical coupled lines (CLs). The S-matrix model is established as a function of the TL and CL parameters.

NGD Analysis of 10-Line Microstrip Structure Crosstalk

2020 International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2020
An analysis of coupling effect between "1" and "0" shape lines is studied in this paper. After the "10" structure description, the two-port equivalent circuit is introduced. The S-matrix model is presented. Then, the 10-structure group delay (GD) is expressed.

NGD: Filtering Graphs for Visual Analysis

IEEE Transactions on Big Data, 2018
Graph visualization finds wide applications in different areas. As the popularity of social network sites is increasing, it becomes particularly useful in visual analysis of these sites. A number of algorithms for graph visualization have been developed over the past decades.

NGD cold-neutron prompt gamma-ray activation analysis spectrometer at NIST

Journal of Radioanalytical and Nuclear Chemistry, 2014
A new instrument for cold neutron prompt gamma-ray activation analysis is being designed as part of the recent expansion of the cold neutron guide hall at the NIST Center for Neutron Research. This instrument has a 10-fold increase in neutron flux and lower gamma-ray and neutron background compared to the PGAA instrument it will replace at NG7.

Familiarity analysis and time-advance experimental study of LP-NGD RC-circuit intended to operate with Unity-normalized gain

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering
PurposeThe purpose of this paper is to develop a familiarity analysis of resistive-capacitive (RC) network active circuit operating with unfamiliar low-pass (LP) type negative group delay (NGD) behavior. The design method of NGD circuit is validated by simulation with commercial tool and experimental measurement.Design/methodology/approachThe present ...
