Methods to Optimize Plasmonic Structure Integrated Single-Photon Detector Designs
Introduction: Predesigned plasmonic structures are capable of enhancing optical phenomena, the key concept is tailoring the integrated devices' composition to engineer the spectral response and near-field distribution [1]. Our previous studies have shown that three-quarter-wavelength ... Read More
Numerical Simulation of the Heat, Mass, and Momentum Transfer During the Microwave Drying of Osmodehydrated Porous Material
Recent studies have been devoted to develop mathematical models to simulate the food processing using the porous media approach. The aim of this study is to simulate the microwave drying of osmodehydrated food by means of modeling the mass, energy and momentum transfer using the porous ... Read More
Analysis and Development of Koch Fractal Dipole Antennas
Devices of mobile communication require smallest sizes of antennas. This is one of the applications of fractal antennas which have reduced size or are multiband and can be used for mobile phone, RFID, Wi-Fi, digital TV, among other applications. The Koch fractal geometry allows better ... Read More
Analysis of 1D, 2D, and 3D Marine CSEM in COMSOL Multiphysics® Software
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 ... Read More
Simulations of Negative Curvature Hollow-core Fiber
COMSOL Multiphysics® software was used to simulate and analyze the transmission attenuation spectra of the negative curvature hollow-core fiber (NCHCF) over the wavelength from 2.7 μm to 4.2 μm. The effect of thickness of capillaries and the effect of the distance between the capillaries ... Read More
The Simulation of Motion of a Slider upon a Stator Due to Frictional Force Using COMSOL Multiphysics® Software
The Surface Acoustic Wave (SAW) linear motor was studied which is developed utilizing the friction principle for driving. The principle says that, when a slider is placed on the Rayleigh waves generated on a stator, the slider moves in reverse direction of the wave due to friction ... Read More
Electromagnetic Well Logs Simulated with the COMSOL® RF Module on a Cluster
Introduction Computer simulations are widely used for the interpretation and inversion of electromagnetic measurements in well logging. Until recently, simulated logs have been computed with approximate 1D or 2D models. By using the COMSOL® RF Module installed on a cluster, we show that ... Read More
