Enhanced Surface Plasmon Polariton Propagation Induced by Active Dielectrics

M. Mattheakis[1], C. Athanasopoulos[1], G. P. Tsironis[1]
[1]University of Crete, Heraklion, Greece

We present numerical simulations for the propagation of surface plasmon polaritons in a dielectric-metal-dielectric waveguide using COMSOL Multiphysics® software. We show that the use of an active dielectric with gain that compensates metal absorption losses enhances substantially ... En savoir plus

Simulation of Light Coupling Reciprocity for a Photonic Grating

V. Kivijärvi[1], M. Erdmanis[1], I. Tittonen[1]
[1]Aalto University, Department of Micro- and Nanosciences, Espoo, Finland

SOI (Silicon on Insulator) technology utilizes silicon components on SiO2 layer. Propagating electric field distribution in a SOI waveguide is called mode of the waveguide. Photonic gratings are formed by etching grooves on the top of a waveguide. Gratings can operate in two directions. ... En savoir plus

Pre-clinical Modelling and Simulation of Hepatic Radiofrequency Ablation

S. Singh [1], R. Repaka [1], ,
[1] Indian Institute of Technology Ropar, India.

Radio-Frequency ablation (RFA) has received a considerable interest as a minimally invasive treatment technique used for destruction of a variety of primary and metastatic hepatic tumors. A parametric study of hepatic radio-frequency ablation using three-dimensional numerical models has ... En savoir plus

3D Modeling of Plasmon Excitation by Grating

G.G. Gentili[1], S. Pietralunga[2], M. Bolzoni[1]
[1]Politecnico di Milano, Dipartimento di Elettronica e Informazione, Milano, Italy
[2]INFN-CNR, Istituto di Fotonica e Nanotecnologie, Milano, Italy

Grating-assisted optical coupling into long-range modes of strip plasmonic waveguides is analyzed by a 3D numerical simulation with COMSOL Multiphysics. We used the RF Module and its scattering formulation. A comparison with results obtained using the common 2D approximated analysis is ... En savoir plus

Electric Field Calculations for AC and DC Applications of Water Controlled Cable Termination

T. Karmokar[1], R. Pietsch[1]
[1]HIGHVOLT Prüftechnik Dresden GmbH, Dresden, Sachsen, Germany

The computation of electric field strength is the state-of-the-art technique for designing and optimizing High-Voltage (HV) equipment. In this research, the equipment under analysis is Cable Termination (CaTr) which is used to apply high-voltage (75 kV – 800 kV AC) on the cable to be ... En savoir plus

Characterization of a 3D Photonic Crystal Structure Using Port and S-Parameter Analysis

[1]University of Michigan, Ann Arbor, MI, USA
[2]Sandia National Laboratories, Albuquerque, NM, USA

We present a 3D port sweep method in a lossy silicon photonic crystal resonator to demonstrate the capabilities of COMSOL Multiphysics® for frequency domain analysis with input and output ports. This method benefits from the advantages of the S-parameter analysis to characterize the ... En savoir plus

Simulation of the Impedance Response of Thin Films as a Function of Film Conductivity and Thickness

Y. Jin [1], S. Kumar [1], R. A. Gerhardt [1],
[1] School of Materials Science and Engineering, Georgia Institute of Technology, Atlanta, GA, USA

Introduction The electrical properties of materials are important in many different applications. In microelectronics for example, films must perform as insulators, semiconductor or as conducting layers. In recent years, scanning probe methods are being extended to the nanometre scale ...
