ABSTRACT
A surface micro machined capacitive switch has been designed and fabricated on a glass substrate. The switch is constructed of a thin metallic membrane crossing over an electroplated coplanar wave-guide transmission line. The electrostatic actuation is utilized as the switching mechanism. The actuation voltage is around 50V. The switch showed low insertion loss of 0.1 dB at 10 GHz and 0.4 dB at 25 dB, and isolation of 15dB at 20GHz. This device offers a potential application in tel ....etc

Micro-electro Mechanical Systems (MEMS)

Introduction
The satellite industry could experience its biggest revolution since it joined the ranks of commerce, thanks to some of the smallest machines in existence. Researchers are performing experiments designed to convince the aerospace industry that microelectromechanical systems (MEMS) could open the door to low-cost, high-reliability, mass-produced satellites.MEMS combine conventional semiconductor electronics with beams, gears, levers, switches, accelerometers, diaphragms, microfluidic thrus ....etc

Compound solid state switches such as GaAs MESFETs and PIN diodes are widely used in microwave and millimeter wave integrated circuits (MMICs) for telecommunications applications including signal routing, impedance matching networks, and adjustable gain amplifiers. However, these solid-state switches have a large insertion loss (typically 1 dB) in the on state and poor electrical isolation in the off state. The recent developments of micro-electro-mechanical systems (MEMS) have been continuously providing new and improved paradigms in the field ....etc

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....etc
