This paper presents techniques for modeling annealed proton exchange (APE) and reverse proton exchange (RPE) waveguides in periodically poled lithium niobate for application to optical frequency conversion. A combination of time-dependent diffusion modeling and electromagnetic mode ... 詳細を見る

A computer controlled microwave exposure system and specialized applicators were constructed for the purpose of facilitating accurate observations of microwave radiation effects on uninfected and infected biological tissue in vitro and in vivo under different electromagnetic modalities ... 詳細を見る

Introduction: Domestic microwave ovens are widely used to heat food products, because of rapid and convenient heating. Nonuniform heating is the biggest issue in microwave heating process, which also causes food quality and safety issues. Microwave heating models are promising tools to ... 詳細を見る

The traditionally magnetic design process involves guessing at a reasonable conductor geometry, using finite element analysis (FEA) software to calculate the resulting fields, and modifying the configuration iteratively to reach an acceptable solution. Taking the opposite approach, we ... 詳細を見る

Soil’s electromagnetic properties adversely affect the performance of electromagnetic induction (EMI) sensors and if conditions are severe enough, render them useless. A simple circuit model is often used to express the electromagnetic induction response of a target analytically. This ... 詳細を見る

We have developed Thor: a pulsed power accelerator for performing dynamic material experiments. The design was aided by using the COMSOL Multiphysics® software with the AC/DC Module and RF Module. Our design process involved optimizing the impedance of the system while maintaining a good ... 詳細を見る

Electromagnetic simulation of light wave interaction at around a tip of single mode optical fiber, which is formed of circular truncated cone shape, has been studied numerically by COMSOL Multiphysics and the RF Module (and Wave Optics Module). The fiber tip has specific nanostructure of ... 詳細を見る

Dehydrogenation of ethylbenzene with a magnetite catalyst has been performed with a fixed bed flow type reactor under microwave irradiation. Microwave heating showed a temperature gradient in the catalyst bed. We analyzed an electromagnetic field and heat transfer in the microwave cavity ... 詳細を見る

High power Terahertz (THz) sources have become a topic of great interest for a wide variety of applications from medical science to security systems and from material science to telecommunication. The high output power of these THz sources mainly depends upon high current density and ... 詳細を見る
