Simulation of Electromagnetic Enhancement in Transition Metamaterials using COMSOL
Metamaterials are a new class of artificial materials, which possess various unusual properties. One of these properties is a negative index of refraction produced by setting both the dielectric permittivity ε and the magnetic permeability μ of the material less than zero. Unique ...

Stochastic Modeling of Biological Systems – Ranking the Model Parameters of the Human Vocal Folds
Computational models of biological systems are becoming more and more common in medical research areas. Evidence of this can be found by examining the number of articles containing the term “finite element” in the expansive National Institutes of Health (NIH) digital research archive ...

Stress Field Simulation for Quantitative Ultrasound Elasticity Imaging
Finite element models using COMSOL Multiphysics and MATLAB were developed to solve the problem of stress distribution interior homogeneous, isotropic, incompressible elastic solid material under known vertical external compression with a rectangular contact surface. Moreover, comparison ... Per saperne di più
Study of Fluid and Mass Adsorption Model in the QCM-D Sensor for Characterization of Biomolecular Interaction
Increasing attention has been paid to application of the quartz crystal microbalance with dissipation (QCM-D) sensor for monitoring biomolecular interactions. This paper focuses on a practical application of protein-protein binding affinity measurement at low concentrations and minimal ... Per saperne di più
The Effect of a Correlated Surface Roughness and Convection on Heat Conduction
Heat conduction through a slab, 0 ≤ x ≤ W is one dimensional. However, if one of the edges, say x=0, is rough the conduction will be two dimensional. The two dimensionality varies with the correlation length with a maximum at a length approximately 10% of the slab width. ... Per saperne di più
Viscous damping of a periodic perforated MEMS microstructure when the Reynolds’ equation cannot be applied: Numerical simulations
This paper develops a computational model for determining the total damping coefficient for a unit cell of a MEMS microscale device containing a repetitive pattern of holes. The basic cell of the microstructure is approximated by an axi-symmetric domain and the velocity and pressure ... Per saperne di più
Importance of Assembly Discontinuity Factors In Simulating Reactor Cores Containing Highly Heterogeneous Fuel Assemblies
To assess the importance of assembly discontinuity factors (ADF), a highly heterogeneous reactor core was simulated using a COMSOL model in which ADF are not used. The resulting errors in assembly powers were found to be unacceptably high. This indicates that for highly heterogeneous ... Per saperne di più
Expanding Your Materials Horizons
Materials and their related properties are intrinsically fundamental to the creation, development and solution of viable exploratory models when using numerical analysis software. In many cases, simply determining the location, availability and relative accuracy of the necessary material ... Per saperne di più
A Study of Lubricating Flows in MEMS Bearings
The bearing and shaft are part of a safe and arm device constructed as an assembly by a multi-layer additive/subtractive plating and planarization processes (EFAB technology). Devices are constructed by a multi-layer additive/subtractive planarization process. This paper evaluates the ... Per saperne di più
Wireless Interaction of Neighboring Two Arm Archimedes Spiral Coils in the RF Electromagnet Range
The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from two arms Archimedes spiral coils. The frequency spatial wavelengths relative to the coil dimensions are in a range where the electromagnetic Maxwell’s ... Per saperne di più
