In many applications, it is desirable to synthesize an adaptive impedance to match some "real world" system, so that when the target impedance changes, the matching impedance tracks this change and maintains a close match. In this paper we present a scheme for adaptive impedance matching formulated in the Model Reference Adaptive Systems' Control (MRAS)

Solid State Phenomena, 2013
Electrically small antenna suffer from the high Q impedance such as narrow bandwidth and poor gain. To improve them, passive impedance matching is often used but it is restricted to a Bode-Fano limit. To skip it, active matching incorporating non-Foster circuits can provide a good solution.

Impedance Matching (Correspondence)
IRE Transactions on Microwave Theory and Techniques, 1955Matching an impedance to a transmission line by the use of a cascaded section of line is a well-known process. However, the range of terminating impedance that can be matched by this method, I believe, is not so well-known. Consider a lossless line of characteristic impedance R/sub0/ to which is to be matched an arbitrary impedance /bar Z/ = R + jX by ...

Determination of the Impedance Matching Domain of Impedance Matching Networks
IEEE Transactions on Circuits and Systems I: Regular Papers, 2004This paper investigates the impedance boundary of impedance matching networks analytically, graphically representing the resultant impedance matching domains. A set of explicit equations is derived to allow the rapid development of the impedance boundary of such networks.

Adaptive Impedance Matching System
2010 International Forum on Information Technology and Applications, 2010In order to resolve the real-time, fast and stable matching problems as to the dynamic load of microwave plasma, including O2, N2, CF4, NF3, N2H2, etc, through the introduction of six-port test theory and impedance matching theory, the authors put forward a new method called automatic impedance match, which calculated reflectance using the FDTD ...

A fundamental skill required in shock wave physics [1–4] is to determine the P-u states behind shock waves after they have reflected from a material boundary or intersect another wave. The best way to understand the resulting shock wave states is graphically using wave propagation x-t graphs combined with P-u graphs.

Impedance matching at arterial bifurcations
Journal of Biomechanics, 1993Reflections of pulse waves will occur in arterial bifurcations unless the impedance is matched continuously through changing geometric and elastic properties. A theoretical model is presented which minimizes pulse wave reflection through bifurcations.
