Efficient Generation of Reduced-Order Circuit and Device Models for Wide Frequency Applications

Mijalkovic S., Wu H.C., Delft University of Technology, NL

An attractive approach to enjoy the accuracy of calibrated physical device models in the circuit design, without computational burdens is the reduced-order modeling (ROM). ROM aims at capturing the most important features of the detailed [...]

A Method for Adding Static External Forcing to Invariant Manifolds

Grinde C., Westby E.R., Vestfold University College, NO

We present a new method for applying quasi-static forcing to invariant manifolds without breaking its invariance. This is usefull for modeling biased reduced-order models. The results from initial simulations are very promising and examples spesific [...]

Liquid Disintegration: Investigation of Physics by Simulation

Zeng J., Korsmeyer T., Coventor, Inc., US

Liquid disintegration includes the processes of formation of droplets and droplet fission. It is important in inkjet printing and in the miniaturization of biochemical analytical devices. This paper reports on an investigation of the mechanism [...]

Mixed-Level Model for Highly Perforated Torsional Actuators Coupling the Mechanical, the Electrostatic and the Fluidic Domain

Sattler R., Schrag G., Wachutka G., Institute for Physics of Electrotechnology, DE

Electrostatic attraction between neighboring electrodes is a widely used actuation principle employed in tiltable micromirrors or microrelays. Electrostatic actuation is especially favored for switching applications in mobile telecommunication because of its low power consumption. State-of-the-art [...]

Triangle Transducer for Micro Electro Mechanical Systems (MEMS) Simulation in ANSYS Finite Element Program

Gyimesi M., Ostergaard D., Avdeev I., ANSYS, Inc., US

The paper introduces a new methodology with a distributed triangle transducer for the strongly coupled simulation of micro electro mechanical systems (MEMS) in ANSYS Finite Element (FE) program.

New Numerical Techniques and Tools in SUGAR for 3D MEMS Simulation

Bai Z., Bindel D., Clark J., Demmel J., Pister K., Zhou N., University of California Davis, US

SUGAR is a modified nodal analysis package for 3D MEMS simulations that owes its heritage and its name to the SPICE family of circuit simulation. SUGAR has undergone the stage of proof-of-concept which showed that [...]
