1. ANN model of RF MEMS Lateral SPDT switches for millimeter wave applications
This paper presents Artificial Neural Network (ANN) implementation for the Radio Frequency (RF) and Mechanical modeling of lateral RF Micro Electro Mechanical System (MEMS) series micro machined Single pole double through (SPDT) switch. We propose an efficient approach based on ANN for analyzing the losses in ON and OFF state of lateral RF MEMS series switch

5. Design of multi-phase micromechanisms using the topology optimization method. / Projeto de micromecanismos multifásicos usando o método da otimização topológica.
A micromechanism is essentially a device of milimetric, or even micrometric, dimensions that can actuate as a gripper, tweezers, clamp, etc. When coupled to an electronic system, they are called "Micro-Electro-Mechanical Systems" (MEMS). Almost all of these devices are constituted by compliant mechanisms, where the motion is allowed by the compliance of its

6. Obtenção e caracterização de filmes finos de oxido, nitreto e oxinitreto de silicio por deposição ECR-CVD / Synthesis and characterization of oxide nitride and silicon oxynitride thin films by ECR-CVD
In this work, silicon nitride (SixNy), oxide (SiOx) and oxynitride (SiOxNy) thin films obtained by remote plasma chemical vapor deposition (RPCVD) on silicon substrate were studied and characterized for micromachining or micro electro-mechanical system (MEMS) applications. Silicon nitride films (SixNy) were used in suspended structures (membranes and bridges
