Scattering loss from magnetic mirror systems-I

Journal of Nuclear Energy. Part C, Plasma Physics, Accelerators, Thermonuclear Research, 1962
In Part I of this paper (BENDANIEL and ALLIS, 1962) the `reference distribution' method for treatment of the problem of scattering loss from a magnetic mirror system was developed. Also the `square well' approximation was treated in detail. Results are now presented of a study in which the `square well' treatment was generalized by the reference ...

Magnetism and mirror symmetry

American Journal of Physics, 1995
Symmetries play an important role in physics. In this article, we examine the relationship between magnetism and mirror symmetry. The reflection properties of the vector potential A(t) and the magnetic induction B(t) are obtained, and these properties are used to analyze some simple circuits.

Magnetic Fluid Deformable Mirrors

2012
The number of new adaptive optics applications has soared during the last decade, demonstrating the need for low-cost, high-stroke deformable mirrors with a large number of actuators. Magnetic fluid deformable mirrors (MFDMs) were proposed a few years ago as an alternative to conventional membrane deformable mirrors used in wavefront correctors. Though

Design applications of magnetic mirrors

Journal of Applied Physics, 1988
Recent developments in permanent-magnet materials have made possible several novel high-field sources, with great potential application in mm/microwave/optical technology. However, even the crude approximations to such structures, which are needed to make their manufacture viable, entail as many as 72 pieces with eight distinct shapes.

Magnetic Mirror on Optical Frequency

Integrated Photonics Research and Applications/Nanophotonics, 2006
We report demonstration of an optical magnetic mirror achieved by nanostructuring a metal surface. In contrast to normal mirrors, it inflicts only small change to the phase of a reflected wave, offering intriguing applications.

Modal dynamics of magnetic-liquid deformable mirrors

Applied Optics, 2014
Magnetic-liquid deformable mirrors (MLDMs) were introduced by our group in 2004 and numerous developments have been made since then. The usefulness of this type of mirror in various applications has already been shown, but experimental data on their dynamics are still lacking.

Cyclotron-resonance maser in a magnetic mirror

Physical Review E, 1999
A cyclotron-resonance maser (CRM) experiment is performed in a high-gradient magnetic field using a low-energy electron beam ( approximately 10 keV/1 A). The magnetic field exceeds 1.63 T, which corresponds to a 45-GHz cyclotron frequency. The CRM radiation output is observed in much lower frequencies, between 6.6 and 20 GHz only.

Magnetic-mirror performance challenges tokamaks

Physics Today, 1976
Results with the Lawrence Livermore Laboratory magnetic-mirror experiments over the past year and a bit are encouraging ERDA to push much harder in that direction, so that mirrors might share some of the funds tokamaks have been attracting. The results on 2XIIB are showing how to stabilize the mirror plasma, increase its value of beta and raise nτ, the

Magnetic mirror by exciting magnetic quadrupole in dielectric metasurface

Journal of Optics, 2019
A type of magnetic mirror entirely dominated by the magnetic quadrupole resonance in a dielectric metasurface consisting of a simple spherical particle square array is designed, with an operating frequency in the far infrared spectrum. The design controls the magnetic quadrupole resonance via the sizes and electromagnetic properties of the particles ...

Magnetic Moments of Mirror Nuclei

Physical Review, 1961
The sum of the magnetic dipole moments for pairs of mirror nuclei, as calculated with intermediate-coupling functions in the $1p$ shell, is found to be very insensitive to the degree of spin-orbit coupling. This property can be understood as being due to the rotational nature of the wave functions, and can also be interpreted in terms of wave functions
