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 spectrum. Fictional cloaking devices have been used as plot devices in various media for many years.
翻译：他是类似于隐身衣这样的东西，它是一种技术，可以让物品像太空船或其他的东西，完全隐身或一部分隐身（就是不要让其它东西可以感应得到那个东西的存在）
