Impedance Matching of Tag Antenna to Maximise RFID Read Ranges & Optimising a Tag Antenna Design for a Particular Application new

M. Yeoman[1], M. O'Neill[2]
[1]Continuum Blue Ltd., Ystrad Mynach, UK
[2]Tumbling Dice Ltd., Newcastle, UK

RFID tags are ever increasing in their daily use, from the monitoring of components, the tracking of produce during processing & production, as well as being used in much of the touch-less technologies seen today. With this technology, there has been the ever increasing need to reduce ... Read More

Antenna and Plasmonic Properties of Scanning Probe Tips at Optical and Terahertz Regimes new

A. Haidary[1], P. Grütter[1], Y. Miyahara[1]
[1]Physics Department, McGill University, Montreal, QC, Canada

A wide variety of near-field optical phenomena such as apertureless near-field scanning microscopy (ANSM) at optical and terahertz (THz) regimes and surface enhanced Raman scattering relies on the electric field enhancement at the end of a sharp tip. Achieving and controlling this ... Read More

Cancer Detection Using Coagulation Therapy with Coaxial Antenna new

S. M. Ali[1], A. K. Jha[1], S. Mahapatra[1], M. Panigrahi[1]
[1]Trident Academy of Technology, Bhubaneswar, Odisha, India

Nearly seven lakh Indians die of cancer, while over 10 lakh are newly diagnosed with some form of the disease every year. Surgical resection is not always feasible in patients with hepatocellular carcinoma. Microwave Coagulation Therapy (MCT) has been used as an alternative to resection ... Read More

Magnetostatic-Magnon Sensors for Microwave Microscopy of Biological Structures new

E. Hollander[1], E. O. Kamenetskii[1], R. Shavit[1]
[1]Microwave Magnetic Laboratory, Department of Electrical and Computer Engineering, Ben Gurion University of the Negev, Beer Sheva, Israel

Microwave sensing and monitoring is very attractive for biological applications because of their sensitivity to water and dielectric contrast. Direct detection of biological structures in microwave frequencies and understanding of the molecular mechanisms of microwave effects is ... Read More

A Design-of-Experiments Approach to FEM Uncertainty Analysis for Optimizing Magnetic Resonance Imaging RF Coil Design new

J. T. Fong[1], N. A. Heckert[1], J. J. Filliben[1], L. Ma[1], K. F. Stupic[2], K. E. Keenan[2], S. E. Russek[2]
[1]National Institute of Standards & Technology, Gaithersburg, MD, USA
[2]National Institute of Standards & Technology, Boulder, CO, USA

The design of a magnetic resonance imaging (MRI) RF coil using finite element method-based analysis is an essential part of a multi-year research project at the National Institute of Standards and Technology, Gaithersburg, Maryland, where the goal of the project is to develop a “phantom” ...

[2]Department of Computational Optimization, University of Szeged, Szeged, Hungary

Introduction: Predesigned plasmonic structures are capable of enhancing optical phenomena, the key concept is tailoring the integrated devices' composition to engineer the spectral response and near-field distribution [1]. Our previous studies have shown that three-quarter-wavelength ... Read More

Simulations of Negative Curvature Hollow-core Fiber new

J. Zhang[1], Z. Wang[1], J. Chen[1]
[1]College of Optoelectronic Science and Engineering, National University of Defense Technology, Changsha, Hunan, China

COMSOL Multiphysics® software was used to simulate and analyze the transmission attenuation spectra of the negative curvature hollow-core fiber (NCHCF) over the wavelength from 2.7 μm to 4.2 μm. The effect of thickness of capillaries and the effect of the distance between the capillaries ... Read More

The Simulation of Motion of a Slider upon a Stator Due to Frictional Force Using COMSOL Multiphysics® Software new

H. B. Nemade[1]
[1]Indian Institute of Technology Guwahati, Guwahati, Assam, India

The Surface Acoustic Wave (SAW) linear motor was studied which is developed utilizing the friction principle for driving. The principle says that, when a slider is placed on the Rayleigh waves generated on a stator, the slider moves in reverse direction of the wave due to friction ... Read More

Electromagnetic Well Logs Simulated with the COMSOL® RF Module on a Cluster new
