  2. Cloaking device - Wikipedia

    en.wikipedia.org/wiki/Cloaking_device

    A cloaking device is a hypothetical or fictional stealth technology that can cause objects, such as spaceships or individuals, to be partially or wholly invisible to parts of the electromagnetic (EM) spectrum. Fictional cloaking devices have been used as plot devices in various media for many years.

  3. Metamaterial cloaking - Wikipedia

    en.wikipedia.org/wiki/Metamaterial_cloaking

    The principle of cloaking, with a cloaking device, was first proved (demonstrated) at frequencies in the microwave radiation band on October 19, 2006. This demonstration used a small cloaking device. Its height was less than one half inch (< 13 mm) and its diameter five inches (125 mm), and it successfully diverted microwaves around itself.

  4. Theories of cloaking - Wikipedia

    en.wikipedia.org/wiki/Theories_of_cloaking

    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 .

  5. Rochester Cloak - Wikipedia

    en.wikipedia.org/wiki/Rochester_Cloak

    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.

  6. Cloak of invisibility - Wikipedia

    en.wikipedia.org/wiki/Cloak_of_invisibility

    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 ...

  7. Active camouflage - Wikipedia

    en.wikipedia.org/wiki/Active_camouflage

    Active camouflage technology, both visual and otherwise, is a commonly used plot device in science fiction stories. The Star Trek franchise incorporated the concept ("cloaking device"), and Star Trek: Voyager depicts humans using "bio-dampeners" to infiltrate a Borg Cube without the antagonists realizing they are there. [18]

  8. Cloak - Wikipedia

    en.wikipedia.org/wiki/Cloak

    Figuratively, a cloak may be anything that disguises or conceals something. In many science fiction franchises, such as Star Trek, there are cloaking devices, which provide a way to avoid detection by making objects appear invisible. A real device, albeit of limited capability, was demonstrated in 2006. [13]
