This paper investigates damping ratio in micro-beam resonators based on magneto-thermo-elasticity. A unique aspect of the present study is the effect of permanent magnetic field on the stiffness and thermo-elastic damping of the micro resonators. In our modeling the theory of thermo-elasticity with interacting of an externally applied permanent magnetic field is taken into account. Combined the...

A hybrid micro-macro-optical shuffle interconnection approach is described. The new concept minimizes distortion in multichip smart-pixel shuffle interconnection systems that use macro-optics to link dense arrays of vertical-cavity surface-emitting laser (VCSEL) sources and matching arrays of detectors. The typical narrow-beam cones of VCSEL's are exploited by use of beam-deflecting micro-optic...

Introduction: The present study aimed to evaluate the impact of PbO nano and micro-sized fillers on ordinary and heavy concretes for different photon energies. Material and Methods: The MCNPX Monte Carlo code (version 2.6.0) was used for all simulations in the present study. A model of narrow-beam geometry was validated and utilized to calcul...

Finite element formulations based generally on classical beam theories such as Euler-Bernoulli or Timoshenko. Sometimes, these two formulations could be problematic expressed in terms of restrictions of Euler-Bernoulli beam theory, in case of thicker beams due to non-consideration of transverse shear; phenomenon that is known as shear locking characterized the Timoshenko beam theory, in case of...

Electron beam bunching in the optical wavelength was observed experimentally for the first time at the Brookhaven Accelerator Test Facility(ATF) using the Inverse Free Electron(IFEL) accelerator. The micro-bunched electron beam has been studied by measuring the coherent transition radiation (CTR). We have experimentally observed a quadratic dependency of the CTR signal with the charge of the el...

There is a huge increase in design of various wireless antennas for daily and commercial use. They are designed with various specifications. After deeply analyzing the comparisons, this paper is a result of comparison of two designs, namely micro strip patch antenna at 2.4GHZ using EZNEC and another micro strip patch antenna at 10.65GHZ using ADS. This comparison differentiates the results base...

A novel microactuated micro-XYZ stage with large travel distance and fine positioning capability has been demonstrated using the surface-micromachming technology. The micro-XYZ stage consists of three inplane translation stages driven by integrated scratch drive actuators. Two vertically stacked 45" micromirrors in orthogonal directions are employed to achieve vertical beam adjustment without u...

An in situ measurement of micro-friction torque in MEMS gas bearings, which has been a challenging research topic for years, is realized by a system designed in this paper. In the system, a high accuracy micro-force sensor and an electronically-driven table are designed, fabricated and utilized. With appropriate installation of the sensor and bearings on the table, the engine rotor can be drive...
