RF thin-film permeability measurements in a travelling electromagnetic field
IEEE International Digest of Technical Papers on Magnetics Conference, 2003Summary form only given. Thin film permeability measurements in the RF range gives useful information for materials science and modem IT device developments including cellular phone (0.8-2GHz) and bluetooth devices (2.45GHz). We propose a new permeameter utilizing traveling electromagnetic field mode and a shielded-loop type planar pickup coil.

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 ...

Analysis of Electromagnetic Field on the Permeability Test of Concrete
2012 Asia-Pacific Power and Energy Engineering Conference, 2012The method of water pressure measuring permeability of concrete has a long test cycle, low efficiency, and doesn't apply to low permeability of concrete. The method based on electricity can overcome these shortcomings. This paper puts forward the method of streaming potential coefficient to measure the permeability of concrete, which is reasonable ...

Computation of electromagnetic field scattered by three-dimensional permeable objects
IEEE Transactions on Magnetics, 1991A surface integral equation is derived for electromagnetic scattering by highly conducting permeable objects of irregular shapes and solved, numerically, using the method of moments. The analysis make uses of the impedance boundary condition to simplify the formulation and reduce the computation time and memory requirements associated with the method ...

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 field quantization in a linear isotropic permeable dielectric medium
Physical Review A, 2004The macroscopic electromagnetic field is quantized in a linear isotropic permeable-dielectric medium by associating a proper damped quantum-mechanical harmonic oscillator with each mode of the radiation field. We introduce a particular form of the Langevin equation with two memory functions and two random impulses to describe the motion of a damped ...
