Nonlinear optical susceptibilities of conducting polymers

Physical Review B, 1990
On considere des systemes electrons-reseau unidimensionnels, a l'aide de l'approche de Genkin-Mednis. En se fondant sur le modele de Su-Schrieffer-Heeger, on etablit une expression analytique de la generation de la troisieme harmonique de ces polymeres ...

Nonlinear bone conducted hearing

The Journal of the Acoustical Society of America
Air conduction (AC) is the typical mode of hearing used by humans. AC process follows a defined path starting at the ear canal, middle ear to the cochlea, and finally to the sensory organs of hearing. The highest frequency we can hear using AC is approximately 20 kHz.

Temperature-dependent nonlinear conductivity and carrier mobility of silicone rubber/SiC composites

IEEE transactions on dielectrics and electrical insulation, 2018
An electrical field distorted by the complicated cable accessory structure and non-uniform temperature distribution is a significant threat to high voltage direct current (HVDC) cable.

Nonlinear High-Frequency Plasma Conductivity

The Physics of Fluids, 1969
Some numerical results for the high-frequency nonlinear conductivity of a fully ionized plasma are presented. Special attention has been given to the case when the frequency ω of the applied electromagnetic field is close to the electron plasma frequency ωp.

Electrical Field Distribution in ±600 kV Converter Transformer Bushing Core with the Application of Epoxy Resin with Nonlinear Conductivity

IEEE International Conference on High Voltage Engineering and Application, 2018
The converter transformer as the conversion center for switching DC and AC is particularly crucial and is the key equipment of HVDC power system. As the weakness of the converter transformer, it is easy for the insulation failure to happen on the ...

Nonlinear THz conductivity in graphene

CLEO: 2014, 2014
We report the nonlinear THz conductivity of graphene. The heating of charge carriers by strong THz pulses results in a reduction of the high-frequency conductivity of graphene, in spite of reduced scattering for high-energy carriers.

Nonlinear conductivity for mesoscopic systems

Physica A: Statistical Mechanics and its Applications, 2002
A generalized Kubo formula for a mesoscopic system is derived describing the conductivity, subject to an (not weak) external electric field, and shown to be expressible in the Landauer-Buttiker form. Using this approach the electrical conductivity of a quantum dot point-contact was expressed as k(2e(2)/h), where k represents the strength of the mutual ...

Nonlinear terahertz conductivity in graphene

2013 38th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2013
Graphene is a unique conductor, where charge is transported by massless carriers. Remarkably, the THz response of carriers strongly depends on the driving field.

Nonlinear observers for conductivity tracking

IFAC Proceedings Volumes, 2010
Abstract Conductivity based sensors can be applied to monitor a wide range of processes in the mineral processing industry. This work compares the use of an Extended Kalman Filter and a Nonlinear Observer for tracking conductivity variations under dynamical conditions.
