Impedance Network for an Automatic Impedance Matching System
2007 Asia-Pacific Microwave Conference, 2007This work presents a RF tunable impedance matching network. It uses a quarter-wavelength (lambda /4) transmission line loaded by a combination of switches, capacitors and inductors. With MEMS-based switches and inductors, the simulation results show that this circuit is capable of correction load reflection coefficients of up 0.5 to better than 0.3 ...

Subversion Impedance in Covert Communication Networks
2012 IEEE 11th International Conference on Trust, Security and Privacy in Computing and Communications, 2012A covert communications network is a connected, overlay peer-to-peer network used to support communications within a group in which the survival of the group depends on: (1) anonymity of communications; and (2) concealment of network membership to both other members of the group and external eavesdroppers.

Network-assisted procedure for impedance dissemination
Proceedings of the 21st IEEE Instrumentation and Measurement Technology Conference (IEEE Cat. No.04CH37510), 2004A technique for disseminating impedance measurement units from National Metrology Institutes to secondary laboratories is proposed in this paper. Such a technique takes advantage of a client-server application over the Internet and employs a commercially available impedance calibrator with computer-interfacing capabilities.

Advanced thermal impedance network for the heat diffusion with sources
International journal of thermal sciences, 2018A new focus is given regarding the use of the quadrupole technique to solve heat diffusion problems with heat source in layered structures. The thermal impedances formalism is used that allows representing the heat transfer in such systems as impedances ...
