We will present the issues of a microreactor setup designed for microwave organic synthesis and demonstrate how COMSOL Multiphysics® is used to understand the mechanism of microwave heating and improve the microreactor design. The RF Module was used for the electromagnetics and solid ... En savoir plus
Project X is a proposed proton accelerator complex at Fermilab. The CW LINAC is based on five types of resonators operating at three frequencies: half-wave, spoke, and elliptical. The low beam current for the CW operation of Project X requires cavities to operate at a high loaded Q and, ... En savoir plus
The generation of terahertz frequency radiation (0.1-10 THz) is an important technological goal due to the use of this non-ionizing radiation to penetrate a wide range of non-conducting materials. One outstanding problem has been the propagation of THz radiation in guided wave devices. ... En savoir plus
Normal conducting cavities are typically used in the front end of proton accelerators to get the beam accelerated to velocities approximately a few tenths of the speed of light, where superconducting cavities can then be used to accelerate the beam to the speed of light. The warm part of ... En savoir plus
The microstrip line is widely used as the planar transmission line in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL Multiphysics® to study multiconductor microstrip systems on microwave integrated circuits. We specifically illustrate ... En savoir plus
Use of the terahertz(THz) region, which is unexplored frequency band, is investigated and expected for the next-generation high-speed wireless communication. In this presentation, we propose a monolithic integrated device by using mesa-shaped compound semiconductor and a thin-metal ... En savoir plus
Electromagnetic waves in the terahertz (THz) region may be useful for non-destructive imaging and biosensing technology. This presentation shows the example of our research aimed at the development of application in the THz region. The result of comparing the FDTD method and COMSOL ... En savoir plus
We are developing a reflective metal-insulator-metal (MIM) filter with narrow band absorption. In the MIM structure, the interaction between subwavelength multilayer and visible light, and the resultant surface plasmon resonance (SPR) in specific illumination conditions must be ... En savoir plus
In order to perform rust surface treatment for stainless wires, we proposed an electrolyzing equipment to do so. It has the following advantages: safer, cheaper and less environmental pollution. To study the performance of the electrolyzing process, numerical simulation for electric ... En savoir plus
Computer simulation is mandatory for the optimization of electromagnetic devices. Here we concentrate on two classes of devices operating in the MHz and GHz range, namely microwave ovens and TEM cells for electromagnetic compatibility testing. In particular we concentrate on the issue ... En savoir plus
