Metamaterial can trap light to become 10 times more magnetic
Metamaterial can trap light to become 10 times more magnetic
Trapping of light is made possible by the material's firmly bound excitons called quasiparticles with robust optical properties.
Metamaterial can trap light to become 10 times more magnetic::undefined
It may often get overshadowed in an age where AI, superconductors and other tech dominate the news but I sincerely belief meta materials will be the biggest game changer anyone of us will know in their lifetime.
Aren't superconductors a meta material?
Can you elaborate? I never heard of meta materials before.
(Half chatgpt half me) Meta materials or nano composites (they have a few names) are materials engineered to have properties not found in naturally occurring materials.
They are designed on a microscopic scale to manipulate electromagnetic waves in specific ways. This can result in unique optical, acoustic, and thermal properties, like being able to bend light or sound waves in unconventional directions. Common applications include advanced optics, wireless communication enhancements, and even invisibility cloaks and self cleaning surfaces in theoretical designs.
There is a really cool tinfoil hat (!!!) story on how we discovered they are possible, Lets say that since certain events in Boston and Roswell The US Air Force seems to have kickstarted and is often involved in this research. In the posted article the The US Air Force Office of Scientific Research was also stated to be funding this research. Take it with a cool grain of salt.
On this day, we are all juggaloes.
What are magnets anyway?
Dammit! *paints black and white clown face.
The article linked here is rubbish, CrSBr is not a meta material and also not a superconductor. It is a layered semiconductor. However, the Nature article they link to is quite interesting. The background is in cavity engineering, which is where one tries to modify intrinsic material properties by coupling to light "strongly". This is usually done by creating a cavity (think two opposing mirrors around the material) and have light bounce back and forth.
Here instead they don't need to use mirrors, but the refractive index is different enough to trap light in the material, and the electronic properties seem to be quite sensitive to the light because the magnetic phase is sensitive to magnetic fields and the different magnetic phases have quite different electronic properties. So all in all they find a strong light-matter coupling but only below 132K (the critical temperature of the magnetic phase).
