Silicon Photonic 2 X 2 Power Splitter with S-Bend Configuration

E. Graham[1], N. Fahrenkopf[2], N. Cady[2]
[1]University at Albany (SUNY), USA
[2]SUNY Polytechnic Institute, USA

Directional couplers are used for the purpose of redirecting, splitting, and combining light in silicon photonic circuits. They are used extensively in data communication applications such as wavelength-division-multiplexing and signal switching [1]. Their functionality is an integral ... Read More

Multiphysics Simulation of Internal Discharge in Nanodielectric

F. Alam¹, MA. Rab²
¹UnitedHealth Group, Minneapolis, MN, USA
²Norfolk State University, Norfolk, VA, USA

This research work investigates the effect of inclusion of small amount (0%, 2% and 6%) of natural Nano fillers on the internal field properties and discharge characteristics of polypropylene films. 3D Models are built to simulate field properties and internal charge in natural ... Read More

Computational and Experimental Study on Electrostatic Properties of Fractal Capacitors

Low Yuen Wei Samuel [1], Athalye Surabhi Sachin [1], Yee Sin ANG [1],
[1] Singapore University of Technology and Design, Singapore

The dielectric properties of heterogeneous media are of increasing interest as many applications exploit the usage of dielectric property detection in bio-imaging, scanning, microwave tomography and other electromagnetic applications. Using Laplace’s equation for non-integer dimensions, ... Read More

Enhancement of Birefringence using Metal-filled Suspended Core Microstructured Optical Fibers

Rajat Kumar Basak [1, 2], Debashri Ghosh [1]
[1] CSIR-Central Glass and Ceramic Research Institute, Kolkata, West Bengal, India
[2] Jadavpur University, Kolkata, West Bengal, India

Microstructured optical fiber (MOF) has carved out a niche in the field of photonics in the last decade. On the other hand, the field of plasmonics is also rapidly emerging as a fascinating research area. Combining the advantages of both these fields therefore seems imperative for newer ... Read More

3-Dimensional Numerical Modeling of Radio Frequency Selective Heating of Insects In Soybeans

S. Wang [1], Z. Huang [1],
[1] Northwest A&F University, Yangling, Shaanxi, China

Radio frequency (RF) heating have potential as alternatives to chemical fumigation for disinfesting legumes. This study was conducted to investigate the feasibility of RF selective heating of insect larvae in 3 kg soybeans packed in a rectangular plastic container using a 6 kW, 27.12 MHz ... Read More

Coupled Electromagnetics-Multiphase Porous Media Model for Microwave Combination Heating

V. Rakesh, and A. Datta
Dept. of Biological and Environmental Engineering, Cornell University, Ithaca, NY, USA

Although microwave heating has been studied in great detail, microwave combination heating has not. This work investigated this in a novel microwave combination system that heats the sample through a combination of microwaves and hot air. The study used a coupled electromagnetics ... Read More

A Study of Optical Sensor Based on Fiber Bragg Grating Using COMSOL Multiphysics^®

C. Gavrila[1] and I. Lancranjan[2]

[1]Technical University of Civil Engineering Bucharest, Bucharest, Romania
[2]Advanced Study Centre, National Institute for Aerospace Research “Elie Carafoli”, Bucharest, Romania

Fiber optic sensors can measure a large range of physical, chemical and environmental variables such as temperature, pressure, shape, position, chemical concentration, moisture, etc. Fiber optic sensors provide measurements in applications where the conventional electrical based sensors ...

Modelling of SiC Chemical Vapour Infiltration Process Assisted by Microwave Heating

G. Maizza[1] and M. Longhin[1]
[1]Dipartimento di Scienza dei Materiali ed Ingegneria Chimica, Politecnico di Torino, Torino, Italy

The excessive presence of residual SiC matrix inter-fiber pores is often the main cause for the very poor mechanical strength and toughness of SiC/SiC composites manufactured by CVI (Chemical Vapour Infiltration) process. This work presents a micro/macro Microwaveassisted Chemical Vapour ... Read More

Modeling of an Optical Black Hole with True Gaussian Beam Incidence

X. Ni[1], A. Kildishev[1], E. Narimanov[1], and L. Prokopeva[2]
[1]Purdue University, West Lafayette, IN, USA
[2]Russian Academy of Sciences, Novosibirsk, Russia

We model an ideal optical black hole device in COMSOL Multiphysics as an electromagnetic scattering problem. The device is illuminated with a Gaussian beam which is focused at a fixed position in horizontal direction (x0) and different positions in vertical direction (y0). The device is ... Read More
