Effect of Electromagnetic Pulse Exposure on Brain Micro Vascular Permeability in Rats
Biomedical and Environmental Sciences, 2009To observe the effect of electromagnetic pulse (EMP) exposure on cerebral micro vascular permeability in rats.The whole-body of male Sprague-Dawley rats were exposed or sham exposed to 200 pulses or 400 pulses (1 Hz) of EMP at 200 kV/m. At 0.5, 1, 3, 6, and 12 h after EMP exposure, the permeability of cerebral micro vascular was detected by ...

Electromagnetic Propagation in Homogeneous Media With Hermitian Permeability and Permittivity
Bell System Technical Journal, 1982The problem of electromagnetic radiation traveling in a general homogeneous, but anisotropic and gyrotropic, medium has been solved. The plane wave representation is used to convert Maxwell's equations into a general eigenproblem, which allows for tensor permeability and permittivity and for electric and magnetic gyrotropy.

Electromagnetic Models for UXO Detection and Classification in Permeable Soils
2008Abstract : Support Vector Machine (SVM) and neural networks (NN), are applied to classifying metallic objects according to size using the expansion coefficients of their magneto-quasistatic (MQS) response in the spheroidal coordinate system. The classified objects include homogeneous spheroids and composite metallic assemblages meant to resemble ...

Effect of Electromagnetic Pulse Exposure on Permeability of Blood-testicle Barrier in Mice
Biomedical and Environmental Sciences, 2008To study the effect of electromagnetic pulse (EMP) exposure on the permeability of blood-testicle barrier (BTB) in mice.Adult male BALB/c mice were exposed to EMP at 200 kV/m for 200 pulses with 2 seconds interval. The mice were injected with 2% Evans Blue solution through caudal vein at different time points after exposure, and the permeability of BTB

Simultaneous inversion of airborne electromagnetic data for resistivity and magnetic permeability
GEOPHYSICS, 1998Where the magnetic permeability of rock or soil exceeds that of free space, the effect on airborne electromagnetic systems is to produce a frequency‐independent shift in the in‐phase response of the system while altering the quadrature response only slightly.

On the time-domain electromagnetic response of a conductive permeable sphere
Journal of Applied Geophysics, 2009The time-domain EM response of a conducting sphere has been subject of past studies with a particular goal of understanding the response of steel unexploded ordnance items. A change in formulas and parameter definition between authors has created inconsistency between published results and analytic formulas.

Quasistatic transient electromagnetic response of a permeable nonuniformly conducting cylinder
Canadian Journal of Physics, 1976The step-pulse response of a permeable and a radially nonuniformly conducting cylinder is obtained. Effects of the conductivity distribution pattern and the magnetic permeability on the transient response are examined in detail. It is found that: (i) the initial response (for t → 0) remains unaffected by both the inhomogeneity and the permeability of ...

Reflection of electromagnetic waves at the corrugated boundary between permeable dielectrics
Journal of Physics D: Applied Physics, 1994The reflectivity of periodically corrugated boundaries between non-lossy, isotropic dielectrics with different magnetic permeabilities is studied in a regime where the grating supports only a specularly reflected order. The propagation direction of the incident plane wave may form arbitrary angles with the normal to the mean surface and with the ...

Scattering of Electromagnetic waves by coaxial ferrite cylinders of different tensor permeabilities
Applied Scientific Research, Section B, 1960The boundary value problem of the scattering of a plane electromagnetic wave normally incident on coaxial ferrite cylinders of different tensor permeabilities is investigated. The expressions for the scattered field are derived in terms of Bessel and Neumann functions of different orders.
