Cantilever vibration modes were simulated with COMSOL Multiphysics. In the 1st approach the model consisted of an excitation piezo, a holder plate and a chip where the cantilever was mounted on. A sinusoidal voltage signal was applied to the piezo in the simulation, which resulted in ... 詳細を見る
COMSOL Multiphysics® is being utilized to develop Thermal Model for Wire Directed Energy Deposition Additive Manufacturing (Wire-DED) process with an objective to analyse the heat transfer phenomenon during and after the process. Wire-DED process’s growing industrial acceptance at a very ... 詳細を見る
The use of LEDs package for lighting presents a thermal problem. In fact, 70% of the energy consumption is converted to heat. This affects widely the LEDs performance especially lifetime and luminous efficiency. Thermal management of LED is interested in natural convection cooling. The ... 詳細を見る
Deep Ultraviolet Light Emitting Diodes (DUV LEDs) are presently operating at a relatively low efficiency, thus large amount of LED driving power is dissipating in heat. Thermal heating degrades LED performance and decreases LED’s lifetime. The degradation of DUV LED devices with ... 詳細を見る
Pulsed DC technology has led to the design of cost-effective deposition systems and to improved film properties, compared to conventional rf systems. In this work, a two-dimensional finite element model is used to investigate the high frequency pulsed DC discharges in nitrogen. The study ... 詳細を見る
Light emitting Diode (LED) has been proved to be the best resource for commercial as well as industrial lighting applications. However, thermal management in high power LEDs is a major challenge in which the thermal resistance (Rth) and rise in junction temperature (TJ) are notable ... 詳細を見る
Numerical simulations can well predict the electric current and temperature distribution in GaN-based LED chips. It can be used to improve the device design and optimization of the LED devices. Future work will include the optical modeling to analyze the optical properties of the LED ... 詳細を見る
The possibility of exploiting the Orbital Angular Momentum (OAM) of light as a means to simultaneously transmit radio signals at the same frequency led us to the experimental implementation of an OAM-based multiplexing scheme between antenna arrays. Within this framework, the realization ... 詳細を見る
Metal-Organic Chemical Vapor Deposition (MOCVD) is used for the manufacture of Multi-Quantum Well Light Emitting Diodes (MQW LEDs). The process uses a carrier gas flow containing a dilute mixture of metal organic precursors, Tri-Methyl Gallium (TMG) and Tri-Methyl Indium (TMI), to ... 詳細を見る
