Multiphysical simulation is a daily-used tool for loudspeaker design and engineering, however it is still a time expensive process that requires specific modeling capabilities. In order to increase engineering efficiency and to broaden the usage of multiphysical simulation, at ... 詳細を見る

New methods of generating high-frequency magnetic fields of tens or even hundreds of millitesla at frequencies exceeding 2 MHz are allowing important new applications for induction heating. These include heating low conductivity ionic solutions in situations where electric or ... 詳細を見る

This work explores the implications of wholly random and non-linear nanostructures on electromagnetic wave propagation within a multiphysics simulation environment. Showcased is a way to noticeably bypass the inaccuracies drawn from the linearity dependency of traditional simulation ... 詳細を見る

Here we present a simulation for evaluation of novel obscurant candidates under high-energy laser (HEL) illumination. This approach incorporates thermal modeling into obscurant characterization, allowing for evaluation of the temperature increase of the candidate obscurants as well as ... 詳細を見る

The Electromagnetic Signatures of Explosives Laboratory (EMXLAB) at the U.S. Department of Homeland Security, Science and Technology Directorate's Transportation Security Laboratory (TSL) supports the test and evaluation of millimeter wave imaging systems through the measurement of the ... 詳細を見る

Directional couplers are used for the purpose of redirecting, splitting, and combining light in silicon photonic circuits. They are used extensively in data communication applications such as wavelength-division-multiplexing and signal switching [1]. Their functionality is an integral ... 詳細を見る

Propagation of radio signals can be significantly affected by the characteristics of the medium in which they travel such that the properties of the propagation path affect both the level and quality of the received signal as well as the distance over which signals can be reliably ... 詳細を見る

Microwave plasma sources with a resonant cavity have been widely used in microwave electrothermal thrusters as an electric propulsion device, in which free-floating plasma is ignited and sustained in a propellant gas. The resonant cavity microwave plasma has become increasingly ... 詳細を見る

Localized Joule heating within integrated circuit (IC) chips is the leading cause of non-uniform temperature distribution within the circuit structure of the chips. Such variation in temperature enhances the biased diffusion of metal atoms along current carrying interconnects, a ... 詳細を見る

This paper presents multiphysics modeling of coupled thermal-electrical behavior across the composite joints formed by highly anisotropic conductivity materials such as carbon fiber reinforced polymers (CFRP) under lightning strike conditions and demonstrates the driving physics behind ... 詳細を見る
