The emergence of electromagnetic metamaterials has given rise to a variety of fascinating applications, including the perfect lens and the optical cloaking device. For a long time the study of the properties of metamaterials was limited to normal incidence only. However, it is extremely important to know the behavior of metamaterials especially in the area of imaging. In this paper, we use COMSOL ...

In biomedical research the use of animal models gives rise to several ethical problems. COMSOL Multiphysics® may be used as a non-animal technique, very useful in overcoming all these concerns. In this presentation a particular application in dermatology is shown. Bioheat equation mode and diffusion approximation were used to design a theoretical model of blue LED light interaction with an ...

The mathematical modeling of the diffusion and reaction of toxic compounds in mammalian cells is tough task due to their very complex geometry. The heterogeneity of the cell, particularly the cytoplasm, and the variation of the cellular architecture, greatly affects the behavior of these toxic compounds. Homogenization techniques have been implemented for the numerical treatment of the model. ...

A qualitative flow analysis by numerical simulation of a fermentation process in a sorghum factory is presented. The simulations were done with the Numerical modeling software, COMSOL Multiphysics. Several flow arrangements were considered in the study and as a result, optimized flow configurations were evolved.

Singlet oxygen (1O2) is the major cytotoxic agent during type-II photodynamic therapy (PDT). The production of 1O2involves the complex reactions among cancer agent, oxygen molecule, and treatment laser light. The light propagation in tumor tissue is described by the diffusion equation. In this work, an optimization routine is developed to fit the [1O2]rx profile to the simulated necrosis ...

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 electromagnetic phenomena occurring at the interface between negative-index materials and conventional ...

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 between these results and analytical solutions was used to further validate that stress drops off with ...

Atherosclerosis causes the deposition of plaque on the inner walls of arteries, which leads to restricted blood flow. Using the balloon angioplasty procedure, stents can be inserted and expanded in the atherosclerotic artery. We used COMSOL Multiphysics Structural Mechanics, Solid Stress-Strain module to perform static, large deformation analyses. Our results show that lower stent stresses were ...

The most common case of crevice corrosion occurs on passive materials such as stainless steels, in oxidizing-chloride environments. A flexible crevice propagation model has been developed to allow parametric studies of the solution. Our main results allow us to establish diagrams of stability of solid and gas phases within the crevice and to evaluate the influence of the external ...
