Polarization spectroscopy of a conducting surface

open access: yesOptics and Spectroscopy, 2001
A method of polarization spectroscopy for a conducting surface characterized by a high sensitivity to the state of the surface and its transition layer is proposed. The method uses excitation of surface electromagnetic waves (SEWs) by a linearly polarized probe beam incident on the surface under study and compensation for the phase shift between the p ...

A nonlinear model for surface conduction [PDF]

open access: yesIEEE Transactions on Magnetics, 1998
A nonlinear conducting layer, at the surface of an insulating material, is modeled by a surface with a conductivity which depends on the tangential field at the interface. The model, formulated for 2D and axial symmetric problems, was embedded in a field computation software based on boundary elements method.

Surface profile prediction and analysis applied to turning process [PDF]

open access: yes, 2008
An approach for the prediction of surface profile in turning process using Radial Basis Function (RBF) neural networks is presented. The input parameters of the RBF networks are cutting speed, depth of cut and feed rate.

Charge Accumulation Characteristics of Nonlinear Conductive SIR Composites under Polarity Reversal Voltage

open access: yesZhongguo dianli, 2020
The HVDC cable accessory is the weak point of the cable system. In order to study the effect of the nonlinear conductivity on the charge accumulation property of SiR cable accessory insulation under polarity reversal voltage, this paper prepared a SiR ...

Acoustoelectric Effect of Rayleigh and Sezawa Waves in ZnO/Fused Silica Produced by an Inhomogeneous In-Depth Electrical Conductivity Profile

open access: yesSensors, 2023
The acousto-electric (AE) effect associated with the propagation of Rayleigh and Sezawa surface acoustic waves (SAWs) in ZnO/fused silica was theoretically investigated under the hypothesis that the electrical conductivity of the piezoelectric layer has ...

Influence of volume and surface conductivity on the transient surface charge characteristics of DC‐GIL insulator under thermal–electric coupled fields

open access: yesIET Science, Measurement & Technology, 2022
Here, the transient surface charge distribution of a basin‐type insulator is investigated under thermal–electric coupled fields. Horizontally installed ±200 kV direct current gas‐insulated transmission lines (DC‐GIL) are employed, and a 3D geometric ...

Which bidomain conductivity is the most important for modelling heart and torso surface potentials during ischaemia?

open access: yes, 2021
Mathematical simulations using the bidomain model, which represents cardiac tissue as consisting of an intracellular and an extracellular space, are a key approach that can be used to improve understanding of heart conditions such as ischaemia.

Exploring surface charge dynamics: implications for AFM height measurements in 2D materials

open access: yesBeilstein Journal of Nanotechnology
An often observed artifact in atomic force microscopy investigations of individual monolayer flakes of 2D materials is the inaccurate height derived from topography images, often attributed to capillary or electrostatic forces.

AMROBS: All-Metal Replicas of Biological Surfaces—A Novel Approach Combining Established Techniques

open access: yesBiomimetics, 2018
Biomimetic work often concerns to biological surfaces and their interaction with the environment. Liquid handling, barrier function and protection against heat, pathogens and predators, to name just a few, require biological surfaces to exhibit specific ...
