Surface-enhanced Raman scattering (SERS) is a fingerprint spectroscopy whose sensitivity is down to single molecule level. The mechanism of SERS is mainly contributed to huge enhancement of local electric field, which originated from surface plasmon resonance of metal nanostructures. It is very important to exactly calculate the local enhancement in the electric field strength for right ...

Glass containing nanoparticles is a promising material for various photonic applications due to the unique optical properties mainly resulting from the strong surface plasmon resonance (SPR) of the silver nanoparticles. The characteristics of the resonance can be modified by varying size, shape and concentration of the particles. A finite element method (FEM) implemented in the software COMSOL ...

The Marine Controlled Source ElectroMagnetic (marine CSEM) is a geophysical method used by the oil industry to investigate resistive targets in the sediments under the ocean floor. In this work we simulate marine CSEM data including 1D, 2.5D and 3D modeling. The results obtained with COMSOL Multiphysics show themselves as a promising tool for the studies of electromagnetic methods in prospecting ...

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 ...

The advent of wireless power transfer (WPT) technology has offered a gradually evolving research field with a multitude of triggering applications, like electric vehicles, bio-medical implants and wireless charging media for consumer electronics. However, since the initial establishment of its principal characteristics, instructive WPT efficiencies have been implemented only for rather small ...

Negative Refractive Lens (NRL) has shown that an optical system can produce images with details below the classic Abbe diffraction limit. This optical system transmits the electromagnetic fields, emitted by an object plane, towards an image plane producing the same field distribution in both planes. Recently, two devices with positive refraction, the Maxwell Fish Eye lens (MFE) (Leonhardt et al. ...

Electromagnetic wave analysis of waveguide has been done in this paper with the help of Finite Element Method (FEM) based COMSOL Multiphysics. The design is further extended by placing conductor on a dielectric slab included in the waveguide to form a shielded microstrip transmission line. The simulated models are analyzed to determine the wave propagation characteristics. The validation is ...

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 ...
