Frequency Response Modeling of Inductive Position Sensor with Finite Element Tools
Position sensors have several applications in the automotive sector. Some of the common examples include automatic gear shifter module, seat position adjustment and accelerator-pedal position modules etc. Because of extreme weather condition, such as dust, humidity and moisture and ... Read More
Multi-Layers Surface Coil Design: Geometry Optimization
Nuclear Quadrupole Resonance (RQN) is a radio frequency (RF) spectroscopic technique that is used to detect quadrupole nuclei such as Nitrogen-14. NQR was found to be a good candidate for detecting narcotics, explosives and medicines [1]. However, due to its low sensitivity the use of ... Read More
Modeling the Interaction of Light with Plasmonic Nanoparticles
Plasmonic nanoparticles have received increased interest due to their numerous potential applications in the field of optics and optoelectronics. Currently such metallic nanoparticles are applied in semiconductor devices, such as light emitting diodes (LEDs) and solar cells. The optical ... Read More
Eigen and Coupled Modes on Nanoparticle Aggregate Arrays
Novel class of artificial optical antennas are of great interest in biosensing applications of nanoplasmonics due to their unique and tunable spectral properties. Silver colloid spheres covered with L-cysteine were studied experimentally by spectroscopy and TEM and numerically by a ... Read More
Micromachined Silicon Integrating Cavities for Far-Infrared Bolometer Arrays
We are investigating gold-plated micromachined silicon integrating cavities for arrays of far infrared Transition Edge Sensor bolometers. We present the results of our simulations and show how we used COMSOL Multiphysics® software to optimize the geometry of the integrating cavity. We ... Read More
Computational Simulation of Gold Core/Shell Nanostructures for Near-Field Transducers in Heat-Assisted Magnetic Recording
A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... Read More
Assessment of the SNR, G-Factor and Relative B1- Fields of Medical Radiofrequency Arrays
MRI relies upon a static magnetic field which creates a net magnetic moment from proton spins and radio-frequency fields are generated to excite this magnetic moment into a perpendicular plane, where it can be detected through the use of an array of conductive loops. The optimal size ... Read More
Impedance Matching of Tag Antenna to Maximise RFID Read Ranges & Optimising a Tag Antenna Design for a Particular Application
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 ... Read More
Antenna and Plasmonic Properties of Scanning Probe Tips at Optical and Terahertz Regimes
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
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
