Analysis of Multiconductor Quasi-TEM Transmission Lines and Multimode Waveguides

S.M. Musa[1], M.N.O. Sadiku[1], and O.D. Momoh[2]
[1]Prairie View A&M University, Prairie View, TX, USA
[2]Indiana University-Purdue University, Fort Wayne, IN, USA

This paper presents an analysis approach of multicondcutor quasi-TEM lines transmission interconnect in a single dielectric region and multimode waveguides using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in ... Per saperne di più

Finite Element Analysis of Multilayer Transmission Lines for High-Speed Digital Interconnects

S.M. Musa, and M.N.O. Sadiku
Prairie View A&M University, Prairie View, TX, USA

In this paper, we consider the finite element modeling of multilayer transmission lines for high-speed digital interconnects. Using COMSOL we mainly focused on the modeling of the transmission structures with both cases of symmetric and asymmetric geometries. We specifically designed ... Per saperne di più

Modeling PIN Photodiodes

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

This paper presents one approach to the modeling of an abrupt junction PIN photodiode light sensor using COMSOL Multiphysics software and the incorporated SPICE® capability. The current model is built using the capabilities of SPICE in COMSOL Multiphysics 4.0. This model demonstrates the ... Per saperne di più

Expanding Your Materials Horizons

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

The concept of virtual prototyping can be found linked to many different keywords in the literature: modeling, look-ahead problem solving, etc. This poster paper briefly discusses the potential real benefits that can be realized through pre-build cost savings, minimization of the number ...

A Biological Gear in the Human Middle Ear

H. Cai, R.P. Jackson, C. Steele, and S. Puria
Stanford University, Stanford, CA, USA

To support high frequency transmission, the mammalian middle ear construction is unique. The middle ear bones are connected through two mobile joints, the malleus-incus joint (MIJ) and the incudostapedial joint (ISJ). These synovial joints, consisting of joint capsule and synovial fluid ... Per saperne di più

COMSOL Assisted Simulation of Laser Engraving

H. Karbasi
Conestoga College, Kitchener, ON, Canada

The main purpose of this paper is to develop a proof of concept software that can simulate the geometry of engraved surfaces and can estimate the depth and width of engraved groove and associated laser parameters. For this purpose, COMSOL has been used to simulate the moving laser beam ... Per saperne di più

Drift-Diffusion and Ballistic Transport Modeling in III-Nitride Multiple-QW Light Emitting Structures

M.V. Kisin, and H.S. El-Ghoroury
Ostendo Technologies Inc., Carlsbad, CA, USA

COMSOL-based modeling software developed at Ostendo Technologies allows detailed simulation of semiconductor lasers and light-emitting diodes. In this work, we study the inhomogeneity of the carrier injection into optically active quantum wells of polar and nonpolar III-nitride light ... Per saperne di più

Coil Systems to Generate Uniform Magnetic Field Volumes

J.C. Olivares-Galvan[1], E. Campero-Littlewood[1],
R. Escarela-Perez[1], S. Magdaleno-Adame[2], and E. Blanco-Brisset[2]
[1] Universidad Autonoma Metropolitana - Azcapotzalco, Mexico City, DF, Mexico
[2] Cipress No. 88, Col. Las Arboledas, La Piedad, MH, Mexico.

This paper analyzes different types of coil systems to produce volumes of uniform magnetic field. Some types of coil system are presented in this paper such as Helmholtz, Merritt, and Ruben coil systems. In the study coil systems are intended to produce a magnetic flux density of 2µT in ...

Effects of Shear-thinning and Elasticity in Flow around A Sphere in A Cylindrical Tube

D. Song[1], R.K. Gupta[1], and R.P. Chhabra[2]
[1]West Virginia University, Morgantown, WV, USA
[2]Indian Institute of Technology, Kanpur, India

A sphere sedimenting in a cylindrical tube filled with non-Newtonian fluids, including purely viscous and viscoelastic type, is of both practical and fundamental interest. To investigate the effects of shear-thinning and elasticity, four representative constitutive equations are adopted, ... Per saperne di più

Modeling Neural Tissue and Membrane Behavior During Far-field Current Injection

R. Sadleir[1], A. Minhas[2], and E.J. Woo[2]
[1]University of Florida, Gainesville, FL, USA
[2]Kyung Hee University, Seoul, Republic of Korea

In an earlier work we developed a finite element bidomain model of an aplysia abdominal ganglion in order to estimate the sensitivity of this contrast mechanism to changes in cell membrane conductance occurring during a gill-withdrawal reflex. We used our model to determine both current ... Per saperne di più
