Mitochondrial Membrane Permeability After Nanosecond Electromagnetic Pulsed Exposure

2018 20th International Symposium on High-Current Electronics (ISHCE), 2018
The purpose of the presented study was to reveal the possibility to induce electric pores and/or to open permeability transition pore in the mitochondria of normal and tumor cells after nanosecond pulsed electromagnetic exposure. Cell suspensions were exposed to two type of pulses: 10GHz microwave pulses with duration of 100 ns and 1.0 GHz RF pulses ...

Electromagnetic Characterization of Hydraulic Fracture Shape and Permeability

Proceedings, 2015
Our numerical proof-of-concept studies demonstrate that surface electric field measurements can provide sensitivity to both the geometric distribution of injected conductive fluids and or conductively enhanced proppant as well as sensitivity to the created hydraulic permeability of the fracture zone.

Electromagnetic response of a permeable inhomogeneous conducting sphere

Geoexploration, 1973
Abstract Electromagnetic response of a two-layered spherical model to a dipolar field has been calculated considering the simultaneous influences of a permeable conducting cover, magnetic permeability contrast with the surrounding medium, and radial conductivity variation inside the core.

Current Sheet Permeability in Electromagnetic Pulsed Plasma Thrusters

38th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2002
A case is made for the existence of permeability of current sheets in electromagneticpulsed plasma thrusters. Permeability refers to the leakage of plasma or neutral par-ticles behind the sheet and could cause a significant effect on the performance of thethruster. Analytical calculations are presented which demonstrate the mismatch be-tween experimental

The impact of non-linear permeability on electromagnetic stator core tests

7th IET International Conference on Power Electronics, Machines and Drives (PEMD 2014), 2014
Routine electromagnetic testing is used to detect developing faults in the stator cores of large electrical machines. However the non-linear permeability and hysteresis of electrical steel cause the development of harmonics in the magnetic field, potentially affecting fault interpretation.

Permeability enhancement of Kv1.2 potassium channel by a terahertz electromagnetic field

The Journal of Chemical Physics, 2023
As biomolecules vibrate and rotate in the terahertz band, the biological effects of terahertz electromagnetic fields have drawn considerable attention from the physiological and medical communities. Ion channels are the basis of biological electrical signals, so studying the effect of terahertz electromagnetic fields on ion channels is significant.

Transient electromagnetic response of a permeable nonuniformly conducting sphere

Journal of Applied Physics, 1975
Quasistatic response of a nonuniformly conducting and magnetically permeable sphere to a step pulse is obtained. the effect of conductivity distribution pattern and permeability of the sphere on the transient response is examined in detail. The results show that the introduction of conductivity inhomogeneity has considerable effect on the observed ...

Negative-permeability electromagnetically induced transparent and magnetically active metamaterials

Physical Review B, 2010
tions, but currently their performance is limited by the occurrence of losses—particularly radiation losses, which dominate over their dissipative counterparts even in the optical regime. Here, a metamaterial configuration is conceived that judiciously generalizes the traditional electromagnetically induced transparency EIT scheme—by which radiation ...

Analytical Mode III electromagnetic permeable cracks in magnetoelectroelastic materials

Computers & Structures, 2011
Fracture mechanism is pertinent to minimize the catastrophic failures and optimize the structural design. An exact treatment on the electromagnetic permeable crack problems in a magnetoelectroelastic medium is presented by establishing a Hamiltonian system in terms of the symplectic eigenfunctions. The coefficients of the series are determined from the

Broadband electromagnetic induction response form conducting and permeable spheroids

SPIE Proceedings, 2001
Broadband electromagnetic induction (EMI) methods are promising in the detection and discrimination of subsurface metallic targets. We compute EMI responses from conducting and permeable spheroids by using a field expansion method which is based on the separation of variables in spheroidal coordinates. In addition to an exact formulation which utilizes
