A Parametric Model of Mems Capacitive Switch Operating at Microwave Frequencies

This paper is focused on the creation of an efficient electromagnetic model of MEMS switches which operates at microwave frequencies. The switches are first characterized using a full wave analysis based on finite element method aiming to extract the S-parameters of the switches for different geometrical dimensions. From the S-parameter data base, a scalable lumped circuit model is extracted to...

Generating Efficient Dynamical Models for Microelectromechanical Systems from a Few Finite-Element Simulation Runs

In this paper, we demonstrate how efficient loworder dynamical models for micromechanical devices can be constructed using data from a few runs of fully meshed but slow numerical models such as those created by the finiteelement method (FEM). These reduced-order macromodels are generated by extracting global basis functions from the fully meshed model runs in order to parameterize solutions wit...

Silicon nanostructure cloak operating at optical frequencies

The ability to render objects invisible using a cloak (such that they are not detectable by an external observer) has long been a tantalizing goal1–6. Here, we demonstrate a cloak operating in the near infrared at a wavelength of 1,550 nm. The cloak conceals a deformation on a flat reflecting surface, under which an object can be hidden. The device has an area of 225 mm and hides a region of 1....
