Atmospheric Microwave Plasma

T. S. Marquardt [1], D. F. Shewamene [1], J. J. Swanson [1],
[1] Integrated Engineering, Minnesota State University, Mankato, MN, USA

Plasma gasification of biomass is emerging as an efficient way to reduce the carbon foot print of waste management while generating renewable energy. In general, gasification is a process where electromagnetic wave energy is used to heat biomass sufficiently to convert the bio-mass to ... En savoir plus

Steady-State and Transient Electrothermal Simulation of Microheater for Gas Sensing

A. N. Radwan [1], M. Mehregany [1],
[1] Case Western Reserve University, Cleveland, OH, USA

Microheaters used for gas sensing applications have been studied analytically and experimentally. Previously reported microheaters at COMSOL® conferences have shed light on microheaters’ thermal properties, optimized geometries and power consumption—all based on steady-state analysis. In ...

Relativistic Quantum Mechanical Wave Functions for Fermion Particles in Electric or Magnetic Fields

A. J. Kalinowski [1],
[1] Consultant / East Lyme, CT, USA

INTRODUCTION: The Dirac equation is employed in particle physics and historically gave the first combined unification of quantum mechanics and relativity theory by introducing a four component wave function Ψi. This wave function described the behavior of fermion type particles (e.g. ... En savoir plus

HIIPER Space Propulsion Simulation Using Plasma Module

Z.Chen [1], E. Ziehm [1], G. H. Miley [1],
[1] University of Illinois at Urbana-Champaign, Urbana, IL, USA

The Helicon Injected Inertial Plasma Electrostatic Rocket (HIIPER) is an electric space propulsion concept to generate denser ion and electron beams using inertial electrostatic confinement (IEC) fusion theory and helicon source. Helicon source is employed to generate the plasma and the ... En savoir plus

Finite Element Modeling of a Microwave Cavity under Resonant Conditions

T. W. Krause [1], F. Liu [1], S. Gauvin [2],
[1] Department of Physics and Space Science, Royal Military College, Kingston, ON, Canada
[2] Department of Physics, Engineering Physics and Astronomy, Queens University, Kingston, ON, Canada

A tapered cylindrical microwave resonant cavity, a frustum, also commonly known as an EM Drive, has been reported to produce thrust by the generation of EM radiation within a resonant cavity without using any propellants. In order to determine how a sealed microwave cavity can produce ... En savoir plus

COMSOL Multiphysics® as a Tool for Biomedical Engineering Students to Harness Physical Processes

J. Bush [1],
[1] Old Dominion University, Norfolk, VA, USA

The field of Biomedical Engineering is expanding at an exponential rate. As we began to unravel clues about our complex biological vessels, we uncovered more questions than answers. Our collective curiosity has led biomedical engineering into a broadening field by study of physiological ... En savoir plus

Analysis of D-Shaped Toroidal Superconductive Coils for Medium Size Fusion Experiment Facility

V. Cocilovo [1],
[1] ENEA Frascati Research Center, Frascati, Italy

The research in magnetic confinement fusion is carried out through electromagnetic machines, with a toroidal geometry, where a hot plasma of heavy hydrogen isotopes (deuterium and tritium) is contained in a vacuum vessel. Due to the very high temperatures reached by the plasma, strong ... En savoir plus

Generation of Divergence-Free Bessel-Gauss Beam from an Axicon Doublet for km-Long Collimated Laser

C. Daengngam [1], S. Boonsit [1], P. Kalasuwan [1], P. van Dommelen [1], P. Srisamran [1],
[1] Department of Physics, Faculty of Science, Prince of Songkla University, Songkhla, Thailand

A well-collimated intensity profile at long distance has long been a desired laser property crucial for many potential applications. Extending a non-diverging range for ordinary laser beyond kilometers scale would permit superior performance for optical technologies, including LIDAR, or ... En savoir plus

Computational and Experimental Study on Electrostatic Properties of Fractal Capacitors

Low Yuen Wei Samuel [1], Athalye Surabhi Sachin [1], Yee Sin ANG [1],
[1] Singapore University of Technology and Design, Singapore

The dielectric properties of heterogeneous media are of increasing interest as many applications exploit the usage of dielectric property detection in bio-imaging, scanning, microwave tomography and other electromagnetic applications. Using Laplace’s equation for non-integer dimensions, ... En savoir plus

Dielectric Properties of Heterogeneous Media with Inclusion of Fractal Media

Athalye Surabhi Sachin [1], Muhammad Zubair [1],
[1] Singapore University of Technology and Design, Singapore

The aim of this research is to study the electrostatic properties of heterogeneous media that have fractal geometries. Currently, composite dielectrics are assumed to have regular geometric structures (integer-based dimensions) and an isotopic, homogeneous dielectric permittivity; but, ... En savoir plus
