A cloaking device is a theoretical 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. However, over the entire spectrum, a cloaked object scatters more than an uncloaked object. Fictional cloaking devices have been used as plot devices in various media for many years. Developments in scientific research show that real-world cloaking devices can obscure objects from at least one wavelength of EM emissions. Scientists already use artificial materials called metamaterials to bend light around an object.〔Sledge, Gary. "Going Where No One Has Gone Before", ''Discovery Channel Magazine'' #3. ISSN 1793572-5〕 ==Conceptual origins== Inspired in part by the 1958 film ''Run Silent, Run Deep'', ''Star Trek'' screenwriter Paul Schneider imagined cloaking as a space-travel analog of a submarine submerging, and employed it in the 1966 ''Star Trek'' episode "Balance of Terror". Another ''Star Trek'' screenwriter, D.C. Fontana, coined the term ''cloaking device'' for the 1968 episode "The Enterprise Incident". Writers and game designers have since incorporated cloaking devices into many other science-fiction narratives, including ''Doctor Who'', ''Star Wars'', and ''Stargate''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「cloaking device」の詳細全文を読む スポンサード リンク
