[1]Dresden University of Technology, Semiconductor and Microsystems Technology Laboratory, Dresden, Germany
[2]Forschungs- und Applikationslabor Plasmatechnik GmbH, Dresden, Germany

The plasma enhanced chemical vapor deposition process with a linear plasma source and the frequency range up to 140 MHz developed by Dresden University of Technology and FAP GmbH Dresden enables a fabrication of thin film silicon layers at very high deposition rates. However, an increase ... Mehr lesen

A Novel Mechanical Stress Measurement Method Applied to Wind Turbine Rotor Blades

A.H. Hegab[1], J.P. Kaerst[1]
[1]HAWK, University of Applied Sciences and Arts, Goettingen, Germany

Rotor blades for wind turbines are made of GFRP material. They have to be designed to withstand wind and weather over their approximately 20 years of lifetime. The ability to monitor the mechanical stress is crucial in order to reduce maintenance costs and to maximize operational ... Mehr lesen

Simulation, Fabrication and Observation of Plasmonic Halos

F. Ye[1], M. Burns[1], J. Merlo[1], M. Naughton[1]
[1]Department of Physics, Boston College, Chestnut Hill, MA, USA

We present the simulation, observation and systematic study of a novel optical phenomenon, a “plasmonic halo”, wherein optically pumped surface plasmons on circular silver microcavities form confined drumhead modes that, under off-resonant conditions, transform to colorful far field ... Mehr lesen

RF Hot-Zone Location within Rectangular Confined Spaces

R. Rodriguez[1]
[1]University of the West Indies, St. Augustine, Trinidad and Tobago

RF propagation modelling in (30 – 1000 MHz) SAR region for predicting the location and intensities of constructive interference patterns within rectangular confined spaces using waveguide theory and ray tracing techniques. Mehr lesen

Three-Dimensional (3D) Modeling of Heat and Mass Transfer during Microwave Drying of Potatoes

H. Zhu[1][2], T. Gulati[2], A. K. Datta[2], K. Huang[1]
[1]Institute of Applied Electromagnetics, Sichuan University, Chengdu, China
[2]Department of Biological and Environment Engineering, Cornell University, Ithaca, NY, USA

Microwave drying of fruits and vegetables in a domestic oven has been found to result in large textural changes in the product such as puffing, crack formation and even burning due to the inhomogeneous heating of the microwaves. Microwave drying of potatoes is a complex interplay of ... Mehr lesen

Calculation of Capacitances of Symmetrical Triple Coupled CPW Transmission Lines and Multilayer CPW Broadside Coupled Lines Balun

S. Musa[1], M. N. O. Sadiku[1]
[1]Prairie View A&M University, Prairie View, TX, USA

The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, the quasi-TEM analyses of symmetrical triple coupled ... Mehr lesen

Chemical Reaction Under Highly Precise Microwave Irradiation

S. Fujii[1], Y. Wada[2]
[1]Chiba University, Chiba, Japan
[2]Tokyo Institute of Technology, Tokyo, Japan

Chemical reactions conducted under microwave irradiation have high reaction rates and high selectivity, but these reaction rates are not always reproducible. To achieve reproducibility, a solid-state microwave source with an ultra precise oscillator, high power amplifier module (HPA), ... Mehr lesen

Design of a Microreactor for Microwave Organic Synthesis through Microwave Heating Simulations

W. H. Lee[1], K. Jensen[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

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 ... Mehr lesen

Optimization of Mechanical Properties of Superconducting Cavities for Project X LINAC

I. Gonin[1], M. Awida[1], T. Khabiboulline[1], V. Yakovlev[1]
[1]Fermilab, Batavia, IL, USA

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, ... Mehr lesen

Designing and Simulating THz Guided Wave Devices Using Finite Element Techniques

L. M. Hayden[1], D. A. Sweigart[1]
[1]Department of Physics, University of Maryland Baltimore County, Baltimore, MD, USA

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. ... Mehr lesen
