This paper presents the design and implementation of a reconfigurable reflectarray element design using commercially available RF MEMS switches. This reconfigurablity allows for dynamic control of individual radiating elements by electronically manipulating the switch configuration. The reflectarray element chosen here consists of a microstrip patch on the top surface with a slot in the ground ...

This paper reports on the design of a novel ultra low actuation voltage, low loss radio frequency micro-electro-mechanical system (RF MEMS) capacitive shunt switch. The concept of the switch relies on a mechanically unconstrained armature actuated over a coplanar waveguide using electrostatic forces. The minimum actuation voltage of the switch is <2V, with an isolation of 40dB and insertion los...

Optical MEMS have the potential to drastically reduce the size and cost of digital communications and computation systems. However, the multiple technologies (optical, electrical, and mechanical) utilized in optical MEM systems has led to new challenges in the creation of computer aided design tools for these systems. This paper presents a system level opto-electro-mechanical CAD tool, Chatoyan...

Microelectromechanical Systems (MEMS) have gained acceptance as viable products for many commercial and government applications. MEMS are currently being used as displays for digital projection systems, sensors for airbag deployment systems, inkjet print head systems, and optical routers. This paper will discuss current and future MEMS applications.
