Design of a Miniaturized RF MEMS Based Single-Bit Phase Shifter

A. Chakraborty, A. Kundu, S. Chatterjee, and B. Gupta
Jadavpur University
Kolkata
West Bengal, India

This paper presents a novel design of single-bit RF MEMS phase shifter. The basic novelty introduced for phase shifter design in this case, is by scaling down of the lateral dimensions of the conventional RF MEMS shunt switch by 10 times. The Mechanical and Electromechanical analysis ... 詳細を見る

Micromirror is a versatile MEMS device, which finds use in many application areas. In this paper, we have addressed the issues related to the design and behavioral simulation of MEMS based electro-thermal micromirror [Figure 1] for 3D motion. Two types of thermal actuation mechanism are ... 詳細を見る

Design of a RF MEMS Switch

B. Mishra, M. P. S. Naidu, J. Raj, and Z. C. Alex
VIT University
Vellore
Tamilnadu, India

This paper presents a novel design of a RF MEMS Switch. The switch is a capacitive type, which is actuated by an electrostatic force. The structure of the switch consists of a CPW (coplanar waveguides) transmission lines and a suspended membrane. The modelling of switch is done using ... 詳細を見る

MEMS Electrostatic Comb Actuator: A Comparison of Different Structure Designs and Materials using COMSOL 3.5a

S. Kapoor[1], D. Aggarwal[2], and A. Gujjar[1]
[1]University Institute of Engineering and Technology, Kurukshetra University, Kurukshetra, Haryana, India.
[2]Electronics Science Department, University Institute of Engineering and Technology, Kurukshetra University, Haryana, India.

The micro machining technology that emerged in the late 1980’s can provide micron sized sensors and actuators. Actuators are used for the transformation of non- mechanical input energy into mechanical output energy. There are many types of micro- actuation mechanisms, most commonly used ... 詳細を見る

Design and Simulation of a Nano-Wire Based Piezoresistive Pressure Sensor

S. A. Selvin, N. B. Moorthy, G. Anju, and M. Alagappan
PSG College of Technology
Coimbatore
