Effective conductivity of nonlinear composites

Physical Review B, 1992
The perturbation expansion method is used to compute the effective conductivity of nonlinear composite media. We develop perturbation expansions to solve nonlinear partial differential equations pertaining to the electrostatic boundary value problems.

SiC/SiO2 filler reinforced EP composite with excellent nonlinear conductivity and high breakdown strength

IEEE transactions on dielectrics and electrical insulation, 2020
In this paper, silicon carbide/silicon dioxide (SiC/SiO2) filler with core/shell structure, as a filler in epoxy resin (EP), is studied. The effect of the thickness of the SiO2 shell is studied as it affects the microstructure and electrical properties ...

Nonlinear dynamics in cardiac conduction

Mathematical Biosciences, 1988
Electrical conduction in the heart shows many phenomena familiar from nonlinear dynamics. Among these phenomena are multiple basins of attraction, phase locking, and perhaps period-doubling bifurcations and chaos. We describe a simple cellular-automation model of electrical conduction which simulates normal conduction patterns in the heart as well as

Nonlinear excitations and nonlinear phenomena in conductive polymers

Synthetic Metals, 1987
Abstract Semiconductor polymers such as polyacetylene and polythiophene have experimentally demonstrated nonlinear optical processes with characteristic time scales in the sub-picosecond range. Fast transient photoconductivity measurements on trans -(CH)x as a function of temperature and photon energy indicate a relatively high quantum ...

Mixed convective MHD flow of Williamson fluid over a nonlinear stretching curved surface with variable thermal conductivity and activation energy

Numerical Heat Transfer, Part A Applications, 2023
The mixed convection and electrically conducting flow of two-dimensional Williamson fluid across a nonlinear stretched curvy sheet in the presence of suction/injection, variable thermal conductivity, heat sink/source, and activation energy with ...

Disorder-Induced Nonlinear Conductivity

Europhysics Letters (EPL), 1987
We consider an electrical network of resistors in two dimensions. Each resistor has a threshold value for the potential drop below which it becomes an insulator. If the thresholds are randomly distributed, the current flowing through the total network is not proportional to the external voltage.

Nonlinear conductive spectra of ion-conducting polymers

[1991 Proceedings] 7th International Symposium on Electrets (ISE 7), 2002
An ion-conducting polymer, tetraethylene oxide-organosiloxane (TEOS) copolymer, was synthesized and the linear and nonlinear complex conductivities were measured as a function of frequency. Observed spectra were reproduced by taking into account the interfacial and electrode polarizations.

Harmonic voltage response to AC current in the nonlinear conductivity of iridium oxide Ca5Ir3O12

, 2020
We have carried out harmonic voltage response experiments by application of AC current along the c-axis of Ca5Ir3O12, which has a nonlinear electrical conductivity in a non-ordered state. This AC current method can allow us to investigate a detail of the
