images.jpeg, Mar 2021As we understand physics or try to the best ways we can , after reading that MIT made a perfect mirror we cried no! impossible!. yet they do have something to claim here that is both ground breaking and shows amazing possibility's for a discovery that could be one more variable of many in a technological quantum leap. As we have mentored before tech does not progress in a stable linear fashion it plateau's and leaps we are pretty much in a leaping curve right now to be honest. Although the origins of this info is from back in 2013 and maybe before then. things have started to evolve since then.

So basically Physicists at MIT created the first perfect mirror. When light hits the mirror or indeed any other kind of wave, including acoustic and water waves it bounces off perfectly, introducing no distortion and exactly preserving the original image (signal). this tech has great potential for breakthroughs in solar power, lasers, fiber optic networks, or just about anything that involves the reflecting or capturing of light.

your basic conventional mirror in your home works in a very simple way they block the passage of light, and so they have no choice but to reflect. But the reflection is never perfect, with some energy being absorbed by the material, or scattered in different directions. For a human checking their hair or makeup, the lack of accuracy doesn’t matter; but for imagine this loss of perfection when considering reflecting lasers down a hundred miles of optic fiber, or solar power installations, these tiny imperfections can cause a huge drop in efficiency. and the imperfections are accumulative on conventional materials that reflect as the reflections repeat over time and distance.

like many breakthroughs in the world Marin Soljačić and colleagues from MIT’s photonics and electromagnetics group stumbled across this perfect mirror almost by accident. The team was studying behaviour of a photonic crystals , in this case, a silicon wafer with a nano patterned layer of silicon nitride on top this had had holes drilled into it, forming a lattice. The holes were so small that they can only accommodated a single light wave. At most angles, as physics would dictate light was partially absorbed by the photonic crystal, however when using a specific wavelength of red light, at an angle of 35 degrees, the light was perfectly reflected. Every photon that was emitted by the red light source was perfectly bounced back, at exactly the right angle, with no absorption or scattering and no energy loss of those particular photons from the reflection process.

This phenomenon is new and very unexpected. John von Neumann, one of history’s most notable polymaths, theorized a similar phenomenon in 1929, but it had never been demonstrated experimentally. and was claimed to be impossible

“It’s a very different way of confining light,” Soljačić says., A. Douglas Stone, a Yale professor who wasn’t involved with the work, says that this practical demonstration is “very significant, because it represents a new kind of mirror which, in principle, has perfect reflectivity.”since the findings many practical applications for these perfect mirrors have been both practised and theorised, the MIT team is Focused on sussing out exactly what’s going on. This relatively New phenomena once it is understood and more easily replicated should give rise to very new and novel applications. ,

The most obvious application is more powerful and efficient lasers, but concentrated solar power & using mirrors to boil water, and fiber optics could also be improved. presumably, perfect mirrors could be used in these fibers to provide greater range and speed. Different photonic crystals with different patterns of drilled holes should be able to reflect waves with other properties, too,even acoustic, water, and radio. and one of DARPA favourites which they have always been working on since we can remember starting an online presence and that is that the perfect mirror could also be useful for making an invisibility cloak..
