Modeling and Simulation of Damping Resistance of a Cantilever Based Energy Harvester

M. I. Hassan [1], A. Brimmo [1], A. N. Chatterjee [2],
[1] Masdar Institute of Science and Technology, Abu Dhabi, UAE
[2] MEMS Department, GLOBALFOUNDRIES, Singapore, Singapore

The multilayer composite single mass cantilever is a MEMS energy harvester structure. The vibrating structure is under vacuum in hermetic MEMS. However, out-gassing during process integration and fabrication would cause air molecules (e.g. hydrogen, nitrogen, argon, water vapor, oxygen, ... Mehr lesen

[1] STMicroelectronics, France
[2] CEA Leti, France

The integration of high level of stress in field effect transistors is performed through incorporation of intrinsically strained SiGe layers. With the help of COMSOL simulations, we performed two studies addressing the level of stress in the area of interest. In the first case, we ... Mehr lesen

Enhanced Second-Harmonic Generation in AlGaAs Nanoantennas

L. Carletti [1], D. Rocco [1], A. Locatelli [1], C. De Angelis [1],
[1] University of Brescia, Italy

We designed AlGaAs all-dielectric nanoantennas with magnetic dipole resonance at near-infrared wavelengths. These devices are shaped as cylinders of 400nm height and radii varying from 175 nm up to 230 nm. We analyzed volume χ(2) nonlinear effects associated to a magnetic dipole ... Mehr lesen

Simulation of a Thermoelectric Spiral Structure

Energy efficiency and harvest, speed and performance, flexibility and portability are key elements for innovation in the current consumer electronics markets. Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics ... Mehr lesen

FEM Modeling in Robust Design for Graphene-Based Electromagnetic Shielding

S. Elia [1], G. Granata [1], P. Lamberti [1], V. Tucci [1],
[1] University Of Salerno, Italy

Electromagnetic shielding design is usually approached referring to nominal values of the main parameters. This could lead to malfunctioning devices and its performance differ widely from what was really aimed at or, worse, the final design product could even be physically unrealizable. ... Mehr lesen

Calculation of Surface Acoustic Waves on a Piezoelectric Substrate using Amazon™ Cloud Computing
