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.

2007 European Conference on Power Electronics and Applications, 2007
Most inverters designed to date can only perform either voltage-buck or boost operation with buck-boost mode usually attained by introducing additional active semiconductor devices and passive components to the inverters. Although effective, adding active switches will complicate the inverter control, and push up the overall system costs.

Explicit form for impedance of cauer networks
International Journal of Computer Mathematics, 2001In this paper a new procedure is established to obtain in closed form the poles and zeros of the impedance function of a first Cauer Network. The technique involves the continued fraction representation of the corresponding Laplace transform as a rational function whose numerators and denominators can be represented by tridiagonal determinants.

ANTENNA IMPEDANCE MATCHING WITH NEURAL NETWORKS
International Journal of Neural Systems, 2005Impedance matching between transmission lines and antennas is an important and fundamental concept in electromagnetic theory. One definition of antenna impedance is the resistance and reactance seen at the antenna terminals or the ratio of electric to magnetic fields at the input.
