Charging technology for smartphones is improving, and finally, some companies have introduced ultra-fast wireless charging technology, which has been quite slow so far. In line with this development, it seems that charging a smartphone from any device is also possible.
Scientists developed a new device called antilaser, which is said to be capable of perfectly transmitting energy through any room. This invisible beam energy can power a phone or laptop across a room without plugging it into an outlet.

Just as a laser emits light particles or photons one after another in an ordered array, this new anti-laser device works just the opposite. It sucks in photons one by one in reverse order.
In the course of demonstrating this technology, scientists have demonstrated anti-laser receivers capable of receiving about 99,996 percent of the transmitted energy, even in situations such as electronics are moving, objects are in the way, etc. .
The technique, called coherent ideal absorption (CPA), uses one machine to send energy and another to receive it. However, this has one major limitation. This requires symmetry with respect to time reversal, which occurs only in systems without much entropy. This new CPA method used magnetic fields to push photographs so aggressively that time reversal symmetry was lost.
