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 ...

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 considered as a problem of a great importance. Nowadays, however, microwave technique for localized testing biological ...

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 ...

This study is performed to know which central plate geometry is best suited for electrostatically actuated switch. The simulation is carried out in COMSOL Multiphysics, where user is free to model the geometry without depth knowledge about geometrical dependency of electrostatic. The study of the centrally suspended geometrical models such as circle, square and rectangle suspended by two short ...

Introduction: Single-photon detectors capable of ensuring high fidelity read-out of quantum information delivered via photons of specific polarization are crucial in QIP . Our previous studies have shown that different types of one dimensional plasmonic structures enhance the absorptance of p-polarized light [2, 3]. The purpose of present study was to optimize four different types of ...

In this paper will be presented how an electronic system and its components will respond in case of an impact of an external electromagnetic pulse (EMP). In the first instance the coupling process of transient electromagnetic pulses into electronic systems will be shown. Out of that the disturbing signal inside the system, which is necessary for the following simulation, will be described ...

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 ...

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 ...

We are developing a reflective metal-insulator-metal (MIM) filter with narrow band absorption. In the MIM structure, the interaction between subwavelength multilayer and visible light, and the resultant surface plasmon resonance (SPR) in specific illumination conditions must be understood. Such electromagnetic field interactions have been analysed using COMSOL Multiphysics and RF Module.
