Radio-frequency microsystems, or radio-frequency micro-electromechanical systems, are miniaturized electrical components with small mechanically moving parts of micrometer to millimeter dimensions, which are interacting with radio-frequency signals up to terahertz frequencies and provide near ideal electrical properties. Such RF micro-electromechanical components find a wide range of applications including telecommunication, radar technology, remote sensing, medical diagnosis, security and space applications and are, for instance, used in mobile phones for tuning the antenna.
