Calculation of Capacitances of Symmetrical Triple Coupled CPW Transmission Lines and Multilayer CPW Broadside Coupled Lines Balun

S. Musa[1], M. N. O. Sadiku[1]
[1]Prairie View A&M University, Prairie View, TX, USA

The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, the quasi-TEM analyses of symmetrical triple coupled ... Per saperne di più

Finite Element Analysis of Defibrillation Current Density in Pregnant Women

A. Jeremic[1], E. Khosrowshahli[1]
[1]McMaster University, Hamilton, ON, Canada

Although resuscitation during pregnancy is relatively uncommon and rarely causes death, they have a particularly large impact in terms of the mortality of the unborn child and long-term effects on families and society as whole. In this paper, we present a new 3D finite element model of a ... Per saperne di più

Electrophoretic Focusing and Navigation for Intranasal Target Drug Delivery

X. Si[1]
[1]Calvin College, Grand Rapids, MI, USA

Direct nose-to-brain drug delivery circumvents the blood-brain-barrier and has multiple advantages over intravenous delivery. However, its application is limited by the extremely low delivery efficiency to the olfactory region. This study evaluated the feasibility of targeted drug ... Per saperne di più

Computational Modeling of the Electrohydrodynamics Influencing Trace Mercury Adsorption within Electric Utility Electrostatic Precipitators

H. Clack[1]
[1]University of Michigan, Ann Arbor, MI, USA

Anthropogenic mercury (Hg) emissions increase the risk of neurological and neonatal health effects in humans through fish consumption. There are several technological approaches to controlling mercury emissions from coal combustion, including the injection of a powdered mercury sorbent ... Per saperne di più

Inductive Conductivity Measurement of Seawater

R. W. Pryor[1]
[1]Pryor Knowledge Systems, Inc., Bloomfield Hills, MI, USA

The conductivity of seawater directly correlates with the concentration of dissolved salts. This model demonstrates a new approach to the methodology of inductive conductivity measurement of seawater and other liquids. COMSOL Multiphysics® was used to build a parametrically swept model ...

Quench Propagation and Detection in a YBCO Racetrack

G. Escamez[1], C. Lorin[1], T. Wu[1], P. J. Masson[1]
[1]University of Houston, Houston, TX, USA

High temperature superconductors (HTS) such as YBCO coated conductors show great promise for future applications where high magnetic fields are needed. The superconducting state only exists under a critical surface defined in the (J,T,B) space. Quench is the process by which a current ... Per saperne di più

Electrical Conductivity Modeling and Validation in Unidirectional Carbon Fiber Reinforced Polymer Composites

P. Banerjee[1], J. L. Schmidt[1]
[1]Department of Mechanical Engineering and Materials Science, Washington University in St. Louis, St. Louis, MO, USA

Carbon fiber (CF) reinforced polymer composites (CFRP) have begun to replace Al-Zn-Mg alloys in applications which require high strength-to-weight ratios. The anisotropy of CFRP composites is a result of melt crystallized extrusion techniques that impart an inherent directionality to the ... Per saperne di più

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

M. Dong[1], M. Tomes[1], M. Eichenfield[2], M. Jarrahi[1], T. Carmon[1]
[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 ... Per saperne di più

Finite Element Modeling of Pulsed Eddy Current Applied to Ferrous and Titanium Fasteners in F/A-18 Airplane Wing Structure

V. K. Babbar[1], P. R. Underhill[1], T. W. Krause[1]
[1]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada

Pulsed eddy current (PEC) is being developed to detect stress corrosion cracks between fasteners on the inner wing spars of the F/A-18 Hornet aircraft. The spars are located below a thick carbon/epoxy wing skin, and so cannot be detected by conventional eddy current techniques without ... Per saperne di più

Modeling of Multiconductor Microstrip Systems on Microwave Integrated Circuits

S. Musa[1], M. N. O. Sadiku[1]
[1]Prairie View A&M University, Prairie View, TX, USA

The microstrip line is widely used as the planar transmission line in microwave integrated circuits and high speed interconnecting buses. In this paper, we use COMSOL Multiphysics® to study multiconductor microstrip systems on microwave integrated circuits. We specifically illustrate ... Per saperne di più
