Optical magnetic mirror

2006 Conference on Lasers and Electro-Optics and 2006 Quantum Electronics and Laser Science Conference, 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.

Optical magnetic mirrors

Journal of Optics A: Pure and Applied Optics, 2006
We report the first demonstration of an optical magnetic mirror achieved by nanostructuring a metal surface. It reverses the magnetic field of an incident wave upon reflection, acting as an 'optical frequency superconductor'.

Magnetic stimulation study in mirror movements

Journal of Neurology, 1990
A young man with congenital mirror movements was studied by non-invasive magnetic stimulation. Radiological examination showed no craniocervical or pituitary abnormality except for mild atrophy of the right hippocampus. Magnetic stimulation of the motor cortex caused large amplitudes in the ipsilateral hand muscles, indicating the possibility of ...

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.
