Generation of quasistatic magnetic fields

Review of Scientific Instruments, 1979
A prototype switching system has been developed which can switch 20 kA at 230 V furnished by low-voltage dc generators at the National Magnet Laboratory. The energy is used to generate quasistatic magnetic fields in liquid-nitrogen-cooled copper coils for times approaching 1 s. The present arrangement is limited to fields up to 40 T.

Generation of orthogonal lattice fields

Journal of the Optical Society of America A, 2019
Orthogonal polarization singularities have been introduced recently. Generation of orthogonal fields for V-points and C-points singularity entails the use of different combinations of optical elements. Some of the polarization singularity lattice fields generated by interference contain juxtaposed orthogonal C-points but not orthogonal V-points.

Theory of magnetic field generation

Physical Review E, 1996
It is pointed out that fluctuating magnetic fields are generated on an ion time scale in laser-induced plasmas in the limit \ensuremath{\omega}\ensuremath{\ll}${\mathrm{\ensuremath{\omega}}}_{\mathit{pe}}$ where \ensuremath{\omega} is the perturbation frequency and ${\mathrm{\ensuremath{\omega}}}_{\mathit{pe}}$ is the electron plasma oscillation ...

Loss-of-field protection for generators

Electrical Engineering, 1942
THOUGH electrical circuits from generator armature windings outward to utilization apparatus have received much attention from a protective viewpoint in the past 20 years, relatively little attention has been given to generator field-winding protection.

Generalized Depth-of-Field Light-Field Rendering

2016
Typical light-field rendering uses a single focal plane to define the depth at which objects should appear sharp. This emulates the behavior of classical cameras. However, plenoptic cameras together with advanced light-field rendering enable depth-of-field effects that go far beyond the capabilities of conventional imaging.

Generation of Electromagnetic Fields

2018
In Chap. 5 we saw that an electromagnetic field satisfying Maxwell’s equations in vacuum, a radiation field, is a linear superposition of elementary electromagnetic waves. In this chapter we address another fundamental problem of classical electrodynamics: the determination of the electromagnetic field generated by an arbitrary distribution of moving ...

A Generalized Method of Field Quantization

Physical Review, 1953
A method of field quantization is investigated which is more general than the usual methods of quantization in accordance with Bose of Fermi statistics, though these are included in the scheme. The commutation properties and matrix representations of the quantized field amplitudes are determined, and the energy levels of the field are derived in the ...
