An operational, non-fictional cloaking device might be an extension of the basic technologies used by stealth aircraft, such as radar-absorbing dark paint, optical camouflage, cooling the outer surface to minimize electromagnetic emissions (usually infrared), or other techniques to minimize other EM emissions, and to minimize particle emissions from the object.
Theories of cloaking discusses various theories based on science and research, for producing an electromagnetic cloaking device. Theories presented employ transformation optics , event cloaking, dipolar scattering cancellation, tunneling light transmittance, sensors and active sources, and acoustic cloaking .
However, cloaking a human-sized object at visible wavelengths appears to have low probability. [15] Indeed, there appears to be a fundamental problem with these devices as "invisibility cloaks": [16] It's not yet clear that you're going to get the invisibility that everyone thinks about with Star Trek cloaking device or the Harry Potter's cloak ...
The Predator franchise has spawned five movies — including the upcoming prequel film, Prey — and two crossover flicks pitting the titular predator against alien xenomorphs, not to mention ...
The purpose of a cloaking device is to hide something, so that a defined region of space is invisibly isolated from passing electromagnetic fields (or sound waves), as with Metamaterial cloaking. [5] [13] Cloaking objects, or making them appear invisible with metamaterials, is roughly analogous to a magician's sleight of hand, or his tricks ...
Rochester Cloak is a cloaking device which can be built using inexpensive, everyday materials. John Howell, a professor of physics at the University of Rochester, and graduate student Joseph Choi developed the device, which features four standard lenses that allows an object to appear invisible as the viewer moves several degrees away from the optimal viewing positions.
Invisibility Cloak may refer to: Cloak of invisibility, a theme that has occurred in fiction Invisibility cloak (Harry Potter), a specific instance in the Harry Potter series; Cloaking device, technology for partial or full invisibility to parts of the electromagnetic or acoustic spectrums Metamaterial cloaking, a type of cloaking using ...
The Bird-of-Prey is the first Klingon vessel depicted with a cloaking device; all classes chronologically later in the series would also use a cloaking device. The wings of the Bird-of-Prey are able to move, lowering to attack, maintaining just above horizontal in flight mode and raising high when the ship lands.
