Most readers of the Harry Potter franchise experience such wonder, awe and adventure in the magical realm that is Hogwarts and its affiliates, however, researchers at the University of Texas have decided to take that experience to the next level and apply it to real life.
A team of researchers of the university have studied the use of metamaterials which cannot be found in nature and have applied its usage to create an invisibility cloak, according to ExtremeTech.
Many other researching firms have attempted to recreate the magic that is this cloak, however what makes this one stand out from the rest is that it implements the research into the form of an actual cloak. Research prior to this was geared to proving the concept of invisibility rather than producing the actual Harry Potter phenomena. The cloak is ultra-thin, about .15mm thick and utilizes the metamaterials’ negative refractive index to redirect light waves and allow for the creation of superlenses that warp light beyond diffraction limits.
But invisibility is very much advanced and extremely technological. We may even in fact be way too far ahead of ourselves in terms of advancement and discovery. However, co-author Professor Andrea Alu who is currently on the researching team seems to have his spirits in the right place and sees that this brings us closer to the real replication.
According to Metro UK, Alu mentioned more specifications in a statement saying, “When the scattered fields from the cloak and the object interfere, they cancel each other out and the overall effect is transparency and invisibility at all angles of observation. The advantages of the mantle cloaking over existing techniques are its conformability, ease of manufacturing and improved bandwidth. In principle, this technique could also be used to cloak light.”
Though it has not been perfected yet, and may not be for some time, it’s only a matter of time before the team hits a solid stone in the research. The study is still currently underway.
