Influence of chiral objects on spontaneous emission of atoms and molecules is under attention nowadays. The problem of interaction of chiral molecules with one  or two chiral  spheres was solved analytically recently by our group. The analytical results however are very difficult and needed to be calculated carefully. We modify the RF Module of COMSOL Multiphysics® in order to simulate ...
Computational Simulation of Gold Core/Shell Nanostructures for Near-Field Transducers in Heat-Assisted Magnetic Recording - new
Queen's University Belfast, Belfast, Northern Ireland, UK
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 therefore required. The RF Module and COMSOL Multiphysics® software are used to investigate the plasmonic ...

Plasmonics is a new branch of the fascinating field of photonics and develops concepts to quench light beyond the diffraction limit and enhance electromagnetic fields. These enhancements occur in metals as localized surface plasmon polaritons (LSP) a coupling of the surface density oscillations of the electron gas to the incident light. With threedimensional nano-structures of coinage metals ...

Use of the terahertz(THz) region, which is unexplored frequency band, is investigated and expected for the next-generation high-speed wireless communication. In this presentation, we propose a monolithic integrated device by using mesa-shaped compound semiconductor and a thin-metal broadband antenna which is capable in THz operation, and we analyze several characteristics of the device by using ...

We study the spin wave excitation (coherent precession of magnetic moments) in periodically arranged magnetic stripes, i.e., in one-dimensional magnonic crystal (MC). Two approaches have been implemented. We have defined a structure that dispersion relation can be obtained using both approaches and compared them. In general, the approach I has to be used for MCs where the exchange interactions ...

We study the topography influence of levees on the electric resistivity signal obtained with the Radio-Magnetotelluric method. Field measurements have been modeled with COMSOL, using the AC/DC and RF Modules. A levee situated in Orléans along the Loire river (France) has been considered in order to design a model tacking account of the skin depth and the incident wavelength, keeping a constant ...

INTRODUCTION: Researchers in the biomedical field have recently become interested in the potential applications of plasomics. Surface plasmon resonance based on optical properties of metallic nanostructures can be used for detection of special biological targets. Gold nanostructures with different shapes and sizes have been designed to achieve high enhancement factor (EF), wide range of ...

Heterogeneous materials with different phases, are conductive and insulating (dielectric), and are physically present in different natural materials as e.g. atmospheric ice. Jonscher’s proposed ‘universal dielectric response’ is not sufficient for such materials, as it only reflects conductivity as a nonlinear function of frequency, whereas at lower temperatures dipolar vibrations are also very ...

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 of the plasma frequency reduces the electromagnetic wavelength. Therefore, the electric field distribution is ...

At the Fontys University of Applied Physics (The Netherlands) a plasma etcher has been acquired for educational purposes. The machine operates at low power up to 30 Watt and is driven with a magnetic coil at 13.56 MHz. The use of COMSOL Multiphysics software will be discussed to simulate the temperature and mass fractions of the activated and ionized atoms in the gas. The simulations will be ...
