Full-wave Simulation of Light Propagation through a Quarter-wave Plate

C. S. Lin [1],
[1] Pitotech. Co. Ltd., Changhua City, Taiwan

Advances in 3D display technology relies heavily on the birefringence of light as it propagates through various optical components such as quarter-wave plates. While Jones matrix formulation is commonly employed as a convenient means to study optical systems involving such optical ... Read More

RF NEMS Magnetoelectric Sensor Simulation and Demonstration

H. Lin [1], N. Sun [1], N. X. Sun [1],
[1] W.M. Keck Laboratory for Integrated Ferroics, ECE Department, Northeastern University, Boston, MA, USA

RF NEMS Magnetoelectric (ME) Sensor with a ferromagnetic (FeGaB)/ piezoelectric (AlN) thin film heterostructure is simulated, fabricated and measured in this work. To analyze the response of the ME structures, the coupling between the magnetic, elastic and electric field in the two ... Read More

Time Dependent Dirac Equation FEM Solutions for Relativistic Quantum Mechanics

A. J. Kalinowski [1],
[1] Consultant, East Lyme, CT, USA

The paper illustrates the use of COMSOL (via the “Coefficient-Form PDE” option) for obtaining the relativistic quantum mechanics wave function Ψm(x,y,z,t), m=1,4 as a solution to the time dependent Dirac equations. Once having Ψm(x,y,z,t), it can be used to compute the probability ... Read More

Simulation of Molecular Transport of an Electroporated Cell using COMSOL Multiphysics®

[1] Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND, USA

Electroporation is a highly efficient cellular transfection method which is used to inject molecules into living cells. The electroporation involves creating temporary pores in cell membranes using an electrical field. It has been successfully utilized in medicine and biology for ... Read More

Design of a Nucleic Acid Biosensor Using COMSOL Multiphysics®

L. Velmanickam [1], D. Nawarathna [1], V. Jayasooriya [1],
[1] Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND, USA

Cancer is one of the leading causes of deaths worldwide. According to the American Cancer Society, there will be about 700,000 cancer related deaths in US in 2017. Cancer mortality will be reduced if it is detected and treated at the early stages. Previous studies have shown that ... Read More

Virtual Design of a Four-Bed Molecular Sieve for Exploration

T. Giesy [1], R. Coker [1], J. Knox [1], B. O'Connor [1],
[1] NASA Marshall Space Flight Center, Huntsville, AL, USA

Aboard the International Space Station, carbon dioxide is removed from the atmosphere using a four-bed adsorptive separation process, referred to generally as a 4-Bed Molecular Sieve (4BMS). Experience with the current 4BMS design in space has led to a list of areas for improvement for a ... Read More

Effect of Mass Flow Induced by a Reciprocating Paddle on Electroplating

M. Fukukawa [1], L. Tong [1],
[1] Keisoku Engineering System Co. Ltd., Tokyo, Japan

The reciprocating paddle electrochemical plating cells have been widely applied in microelectronics industry [1-2].The reciprocating paddle is often driven over a cathode aspect horizontally by oscillation set outside a plating cell. The paddle reciprocating parallel to a plating side ... Read More
