Analysis of Multiconductor Quasi-TEM Transmission Lines and Multimode Waveguides
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 ... Read More
Finite Element Analysis of Multilayer Transmission Lines for High-Speed Digital Interconnects
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 ... Read More
Modeling PIN Photodiodes
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 ... Read More
Expanding Your Materials Horizons
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
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 ... Read More
COMSOL Assisted Simulation of Laser Engraving
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 ... Read More
Drift-Diffusion and Ballistic Transport Modeling in III-Nitride Multiple-QW Light Emitting Structures
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 ... Read More
Coil Systems to Generate Uniform Magnetic Field Volumes
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
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, ... Read More
Modeling Neural Tissue and Membrane Behavior During Far-field Current Injection
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 ... Read More
