Multi-Frequency Design of an Optimized Microwave Cavity for Plastic Recycling Applications

L. Royo[1], A. Frisa[1], T. García[1], J. Consejo[1]
[1]Fundación CIRCE, Spain

Microwave heating has been used in industry because of its pollution free and rapid heating technique [1]. It consists of an electromagnetic wave that passes through a media with a frequency between 300 MHz and 300 GHz [2] to generate heat in the system. The purpose of the current work ... En savoir plus

Simulation of Silver Evaporation for A Knudsen Effusion Experiment Under Zero Gravity

D. Henriques[1], H. Fritze[2], M. Schulz[2], T. Markus[1]
[1]Hochschule Mannheim, Germany
[2]TU Clausthal, Germany

Material constants are required to develop new materials for the aerospace, automotive and energy industries. With these highly accurate experimentally determined data, complex metallurgical melting processes can be simulated later, for example. The microstructure of the new alloy can be ... En savoir plus

Simulating Obscurants Under High Energy Laser Illumination

S. Du[1], A. Strikwerda[2], J. Miragliotta[2]
[1]Winston Churchill High School, USA
[2]Johns Hopkins University Applied Physics Lab, USA

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 ... En savoir plus

Assessing Reliability of Embedded Resistor Designs in Integrated Circuit

R. Wulandana[1], P. Wang[1], L. McCary[1], S. Alzeq[1]
[1]State University of New York (SUNY) at New Paltz, USA

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 ... En savoir plus
