MIM capacitors are considered equally important devices for the assessment of dielectric charging in RF MEMS capacitive switches. Beside the obvious similarities between the down state condition of RF MEMS and MIM capacitors there are also some important differences. The paper aims to introduce a novel approach to the study of dielectric charging in MEMS with the aid of MIM capacitors by combin...

The MEMS community has a real need for eeective and eecient tools for device design, simulation, and veriication. The Sugar sim-ulator is a state-of-the-art tool for these tasks, but it suuers from several problems. This paper presents M & MEMS, a web-based interface for the Sugar MEMS simulator hosted on the Millennium computing cluster at the University of California at Berkeley. M & MEMS hel...

A broadband MEMS steerable antenna is fabricated on a silicon substrate using bulk micromachining techniques. The MEMS platform utilizes torsion hinges and is capable of rotation around two axes for full beam steering capabilities. The antenna was designed using the Ansoft High Frequency Structure Simulator (HFSS) package and operates between 10-16 GHz with a coplanar feedline routed across the...

RF-MEMS design is made difficult due to the lack of tools capable of simulating both MEMS devices and their surrounding circuits. Often MEMS components can have structures more than 100 times smaller than the surrounding circuit. This paper presents FDTD based techniques that can be used to simulate large structures containing finely detailed components. Particularly, a split-cell modeling tech...

Starting in the early 1960’s, when the integrated-circuit (IC) technology was developed, micromachining and microelectromechanical systems (MEMS) have grown into a broad research field with several commercial successes. Typical applications of MEMS are in physical, chemical and biochemical sensors, as well as in optical systems such as the digital micromirror device of Texas Instruments. From t...

MEMS is an acronym for Microelectro Mechanical Systems, it defines mechanical structures fabricated with IC processing on (most often) silicon wafers. In Europe, MEMS is labeled Microsystems and in Japan it is labeled Micromachines. The term MEMS evolved in the United States in the 1990s. Prior to that period the technology was labeled silicon micromachining . MEMS defines the technology; not s...

MEMS (Micro-electromechanical Systems) becomes important increasingly due to the smarter and smaller fuze used in OICW (Objective Individual Combat Weapon). MEMS Safety and Arming (S&A) device is employed in different platforms and regions for small caliber projectile. Therefore, it is necessary to make a parametric study of the MEMS S&A device in different apply environments and explore the ma...

Recent advances in the Micro Electro-Mechanical System (MEMS) technology have made wireless MEMS accelerometers an attractive tool for Structural Health Monitoring (SHM) of civil engineering structures. To date, sensors' low sensitivity and accuracy--especially at very low frequencies--have imposed serious limitations for their application in monitoring large-sized structures. Conventionally, t...
