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 ...

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.

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.

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

An anisotropic nanosphere in a uniform field

2014 IEEE Benjamin Franklin Symposium on Microwave and Antenna Sub-systems for Radar, Telecommunications, and Biomedical Applications (BenMAS), 2014
Fields internal and external to an anisotropic nanosphere illuminated by a plane electromagnetic wave are expressed using a quasi-static approach. The field expressions obtained are particularly relevant for circuit modeling of nanoparticles. Closed form expressions for angles of refraction are given.

Ferrohydrodynamic flows in uniform and non-uniform rotating magnetic fields.

2006
Ferrofluids are conventionally used in such DC magnetic field applications as rotary and exclusion seals, stepper motor dampers, and heat transfer fluids. Recent research demonstrates ferrofluid use in alternating and rotating magnetic fields for MEMS/NEMS application of microfluidic devices and bio-applications such as targeted drug delivery, enhanced
