A method of evaluating magnetic field strength by correction between uniform and non-uniform field in near-field

2016 IEEE Global Electromagnetic Compatibility Conference (GEMCCON), 2016
This paper describes a new method for predicting the magnetic field strength in near-field for complex exposure situations. The measurement of the exposure level for compliance tests at sites close to a current source in the low frequency range is restricted by an abrupt gradient distribution in the field strength, non-uniform characteristics, and ...

Bloch electron in a uniform electric field

Physical Review B, 1992
A formula for calculating the interband matrix elements of X for a Bloch electron in a uniform electric field is derived, from which it is found that the interband matrix elements of X are only determined by the interband matrix elements of the derivative of the periodic potential. Using this formula with a Kronig-Penney potential leads to nonvanishing

Field uniformity in radiated field immunity tests

2015 IEEE International Symposium on Electromagnetic Compatibility (EMC), 2015
The calibration requirements of radiated immunity tests performed in semi-anechoic chambers and fully anechoic rooms are analyzed by means of electromagnetic computational tools to verify the severity of the allowed tolerance requirements of their anechoic environments.

Optical Absorption in the Presence of a Uniform Field

Physical Review, 1963
Expressions for the absorption coefficient in the presence of a uniform field, of semiconductors and insulators for both allowed and forbidden transitions are derived. The results are expressed in terms of Airy functions, and the limiting cases examined indicate the tunneling mechanism as a possible explanation for the experimentally observed long ...

On uniform fields in heterogeneous media

Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1990
Abstract Uniform elastic strain fields are found in two-phase fibrous media of arbitrary transverse geometry, and in two-phase media of any phase geometry. In initially stress-free fibrous solids, a single uniform field can be created by certain proportionally changing tractions derived from a uniform overall stress.

XI.—Electromagnetic Phenomena in a Uniform Gravitational Field

Proceedings of the Royal Society of Edinburgh, 1932
In two recent papers Professor E. T. Whittaker has solved the electromagnetic equations for the case of a uniform gravitational field. The fundamental tensor associated with such a field makes the Riemannian tensor vanish, since such a field can be transformed away by a suitable choice of coordinates.

GRAPHENE IN A UNIFORM MAGNETIC FIELD

2020
We study monolayer graphene in a uniform magnetic field in the absence and presence of interactions. In the non-interacting limit, for p/q flux quanta per unit cell (p, q are coprime integer), the central two bands have 2q Dirac points in the Brillouin zone (BZ) in the nearest-neighbor model. These touchings and their locations are guaranteed by chiral
