Scanning Impedance Microscopy: From Impedance Spectra to Impedance Images [PDF]
Microscopy Today, 2001 Abstract The properties and performance of electronic devices are crucially dependent on interface-related phenomena. The presence of interfaces can enable electronic device functionality (p-n diodes, solar cells); alternatively, non-functional interfaces can degrade device performance (ohmic vs. non-ohmic contacts).

Impedance-matched hyperlens [PDF]
Optics Letters, 2007 We propose an approach to optical imaging beyond the diffraction limit, based on transformation optics in concentric circular cylinder domains. The resulting systems allow image magnification and minimize reflection losses due to the impedance matching at the input or output boundaries.

Electrophysical properties of ceramic materials based on manganese-containing potassium polytitanates [PDF]
Электрохимическая энергетика, 2022 The new materials obtained in the potassium polytitanate (PPT)–MnSO4 system by modifying PPT in aqueous solutions of manganese sulfate of various concentrations, followed by thermal treatment and annealing at 1080°C, were synthesized and studied.

Impedance scaling and impedance control [PDF]
Proceedings of the 1997 Particle Accelerator Conference (Cat. No.97CH36167), 2002 When a machine becomes really large, such as the Very Large Hadron Collider (VLHC), of which the circumference could reach the order of megameters, beam instability could be an essential bottleneck. This paper studies the scaling of the instability threshold vs. machine size when the coupling impedance scales in a "normal" way.

A Novel Stator Turn Fault Detection Technique by Using Equivalent High Frequency Impedance
IEEE Access, 2020 Stator turn fault is the most serious failure in the electrical machine drive which requires immediate detection techniques. Under such a turn fault, the fundamental change is that the high frequency (HF) impedance of the fault phase is significantly ...

An Effective EMTR-Based High-Impedance Fault Location Method for Transmission Lines
, 2020 This paper summarizes the electromagnetic time reversal (EMTR) technique for fault location, and further numerically validates its effectiveness when the fault impedance is negligible. In addition, a specific EMTR model considering the fault impedance is

A spatial impedance controller for robotic manipulation [PDF]
, 1997 Mechanical impedance is the dynamic generalization of stiffness, and determines interactive behavior by definition. Although the argument for explicitly controlling impedance is strong, impedance control has had only a modest impact on robotic ...

Impedance analysis of new PS internal dump design [PDF]
, 2018 The High Luminosity Large Hadron Collider (HL-LHC) project at CERN calls for increasing beam intensity in the injector chain. In the Proton Synchrotron (PS), a pre-injector of the LHC, these intensities can result in beam instabilities and potential RF ...

Influence of normal and radial contributions of local current density on local electrochemical impedance spectroscopy. [PDF]
, 2012 A new tri-electrode probe is presented and applied to local electrochemical impedance spectroscopy (LEIS) measurements. As opposed to two-probe systems, the three-probe one allows measurement not only of normal, but also of radial contributions of local ...
