射頻共振空腔推進器
Also known as EmDrive - Electromagnetic Drive, radio frequency resonant cavity thruster, EmDrive, Impossible Drive, EM Drive
The EmDrive is a controversial device first proposed in 2001, purported by its inventors to be a reactionless drive. While no mechanism for operation was proposed, this would violate the law of conservation of momentum and other laws of physics. The concept has at times been referred to as a resonant cavity thruster. The idea is generally considered by physicists to be pseudoscience.

射頻共振空腔推進器（RF resonant cavity thruster）或稱相對性推進器是一種尚具爭議性的新型態推進裝置，最常見的稱呼為「電磁推進器」（EmDrive、電磁驅動引擎），由英國航空太空工程師Roger Shawyer發明，他在2000年創建Satellite Propulsion Research 。這種技術可以用來促進交通工具革命，包括地面交通，海洋交通，航空和太空載具。 至2016年底，相對性推進器研究已經逐漸進入主流科學界實驗如NASA，但批評家認為相對性推進器違反動量守恆。一些科學家及美國太空總署林顿·约翰逊太空中心（Eagleworks）實驗室，德國德勒斯登工業大學、西北工業大學已經完成原型設計。目前有一些實驗觀察到相對性推進器產生小型推力，但也受到其他科學家懷疑。目前相對性推進器研究正在進行中，仍沒有令人信服的物理原理出現。2017年 NASA將進行太空實驗。
