A distributed Bragg reflector (DBR) is a periodic structure formed from alternating dielectric layers that can be used to achieve nearly total reflection within a range of frequencies. The main advantage of DBRs over ordinary metallic mirrors is that DBRs can be engineered to have custom ... En savoir plus
The following example solves a pure conduction and a free-convection problem in which a vacuum flask holding hot coffee dissipates thermal energy. The main interest is to calculate the flask's cooling power; that is, how much heat it loses per unit time. This tutorial model treats the ... En savoir plus
It is often not possible to insert a normal microphone directly into the sound field being measured. The microphone may be too big to fit inside the measured system, such as for in-the-ear measurements for hearing aid fitting. The size of the microphone may also be too large compared to ...

The models here showcase several use cases of the Circuit Extractor add-in, which is able to generate electric circuits from solved physics. A more detailed description of this tutorial model can be found in the blog post "Extracting Electrical Circuits from Electromagnetics ... En savoir plus
Mode analysis is a basic tool for a wide range of radiofrequency and wave optics calculations because it allows for the investigation of mode characteristics in complex waveguide structures. In this tutorial model, you can find two examples that demonstrate typical settings and best ... En savoir plus
When producing glass, the glass melt is cooled down through radiation to form the final shape, subjecting it to stresses. Numerical treatment of radiative heat transfer, using the Radiative Transfer Equation (RTE), helps to optimize this process. COMSOL Multiphysics provides three ... En savoir plus
The Czochralski (CZ) method is one of the most important methods for the preparation of monocrystalline silicon. The shape of the crystal, especially the diameter, is controlled by carefully adjusting the heating power, the pulling rate, and the rotation rate of the crystal. This model ... En savoir plus
This example of a plasmonic waveguide filter shows that the waveguide rejects the electromagnetic radiation of the wavelength between 1.4 um and 1.6 um, but allows the rest of the wavelength. The silver material can be modeled using the Drude-Lorentz approximation, with ε∞ = 3.7, ωp = 13 ... En savoir plus
This application demonstrates how the Application Builder in the COMSOL Multiphysics® software can be used to make advanced cable modeling available to a general audience. At its core is a multiphysics model based on the technology introduced in the Cable Tutorial Series. The ... En savoir plus
Optical computing has been a promising paradigm alternative to the current electronic computers. This model simulates an optical 4-by-4 unitary matrix multiplication device based on a network of six Mach–Zehnder interferometers (MZIs). A more detailed description of this model can be ...
