Optical magnetic mirrors without metals
The reflection of an optical wave from a metal, arising from strong interactions between the optical electric field and the free carriers of the metal, is accompanied by a phase reversal of the reflected electric field. A far less common route to achieve high reflectivity exploits strong interactions between the material and the optical magnetic field ...

Fundamental study on optical performance of low-melting-point metal mirrors for space telescopes
The installation of telescopes with larger primary mirrors in outer space is required for the study of the early universe. However, the shipping, assembling and maintenance of the primary mirror are technical challenges.

Isotope Effects in Switchable Metal-Hydride Mirrors [PDF]
Measurements of optical reflectance, transmittance, and electrical resistivity on the switchable mirror systems YHx and YDx show that the absorption of hydrogen induces the same variations as that of deuterium. In both cases there is a weak transparency window for the metallic dihydride (dideuteride) phase and a yellowish transparency in the insulating

CONSTRUCTION OF A PARABOLIC SOLAR COLLECTOR AND COMPARATIVE STUDY OF THE PERFORMANCE OF ALUMINUM-COATED PELLICLE FILM AND ALUMINUM FOIL AS REFLECTING SURFACES [PDF]
Most of the concentrators used in solar thermal systems are made from mirrors or metals with mirror or other highly reflective surfaces. Because mirror is the best reflecting surface for solar collectors and parabolic mirrors are expensive, people in the

MMI resonators based on metal mirrors and MMI mirrors: an experimental comparison
We report, to the best of our knowledge, the first experimental proof of MMI-based resonators. The resonators have been designed and fabricated on a micron-scale silicon photonics platform and are based on different reflectors suitably placed on two of the four ports of 2x2 MMIs with uneven splitting ratios, namely 85:15 and 72:28.
