The effect of metallization thickness on planar transmission lines plays an essential role in microwave integrated circuits and thin film technology, especially in the propagation characterization and the electric field distribution in the structures. The objective of this paper is to ... Read More
Thermal ablation in the head and neck requires accurate thermal dose delivery to target tissue while protecting the structure and function of nearby tissue and organs. In this study, we present a method that allows importing Computed Tomography (CT) scans to COMSOL, in order to model ... Read More
In many groundwater studies, the areal extent of an aquifer is much larger than its thickness so that flow and transport take place primarily in horizontal directions. Thus, the most common type of modeling in practical applications is two-dimensional involving vertically averaged ... Read More
This paper presents a methodology towards designing, analyzing and optimizing piezoelectric interdigitated microactuators using COMSOL Multiphysics. The models used in this study were based on a circularly interdigitated design that takes advantage of primarily the d{;sub}33 ... Read More
COMSOL Multiphysics software, when properly configured, can readily solve modeling problems in the laminar flow regime using the standard Navier-Stokes equations or in the fully turbulent flow regime using the kappa-epsilon model. Failure to solve a particular model is typically ... Read More
A numerical multiphase flow model is proposed to predict the behavior and motion of entrained inclusions in liquid steel, as they enter the orifice of a LiMCA (Liquid Metal Cleanliness Analyzer) sensor for assuring steel quality. The method of measurement is based on the electric sensing ... Read More
Damping is the liminting factor for the reachable maximum deflection. Thus, it is a very important issue for resonant microsystems. In this paper, we present a damping model for out-of-plane comb driven resonant micromirrors. The basic concept of this model is to attribute viscous ... Read More
We use COMSOL Multiphysics to solve time-dependent optimal control problems for partial differential equations whose optimality conditions can be formulated as a PDE. For a class of linear-quadratic model problems we summarize known analytic results on existence of solutions and first ... Read More
Hybrid laser-MIG arc welding has very interesting advantages compared to laser welding or arc welding used separately. It is known that improvement of productivity results in higher welding speeds, thicker welded materials, joint fit-up allowance, better stability of molten pool, and ... Read More
We present time-resolved methods that rely on near-infrared photons to image the optical properties and distribution of fluorescent probes in small laboratory animals. The coupled diffusion equations of excitation and fluorescence photons in highly scattering tissues were solved using ... Read More
