Modeling with Linearly Polarized Plane Waves

Bridget Cunningham | March 20, 2015

COMSOL Multiphysics version 5.0 introduced users to a new background field feature designed for linearly polarized plane waves. Explore the use of this new feature with an example of polarization-dependent scattering from our Model Gallery.

We often need to work with experimental data in COMSOL Multiphysics, usually to represent material properties or other inputs to our model. However, experimental data is often noisy; it contains experimental errors that we do not want to introduce into our simulations. In this blog post, we will look at how to fit smooth curves and surfaces to experimental data using the core functionality of COMSOL Multiphysics.

Want to share your simulations with the world or simply your own team? After you build an application with the Application Builder in the COMSOL Multiphysics® software, you can share your app using a COMSOL Server™ license with anyone from colleagues to customers. Here is your introduction to COMSOL Server™ — what it is, why to use it, and a brief overview of how to get started.

The biological and chemical processes behind the development of biopharmaceuticals have an important effect on product quality. With its ability to deliver quick results at a lower cost, simulation is a valuable resource in studying and optimizing these techniques. Learn how COMSOL Multiphysics can benefit your modeling of biopharmaceutical processes.

Today, we welcome a new guest blogger, Alexandre Oury of SIMTEC. He discusses the analysis of current distributions in a molten salt electro-refiner. In a webinar highlighting electrochemical recycling processes, SIMTEC presented a computational approach for predicting current distributions in a molten salt electro-refiner. The three main types of current distribution (primary, secondary, and tertiary) were treated, with a particular emphasis on the first two types. Using COMSOL Multiphysics, we implemented primary and secondary current distributions in an electrolysis cell.

When using the COMSOL Multiphysics software to simulate wave electromagnetics problems in the frequency domain, there are several options for modeling boundaries through which a propagating electromagnetic wave will pass without reflection. Here, we will look at the Lumped Port boundary condition available in the RF Module and the Port boundary condition, which is available in both the RF Module and the Wave Optics Module.

A recent study from researchers at the University of Portsmouth has deemed limpet teeth as the strongest biological material known today. We shed light on the unique properties of this material and how it compares to its predecessor: spider silk.

Gustav Robert Kirchhoff was a German physicist famous for his vast contributions to the study of spectroscopy, electrical circuits, thermochemistry, and more. Kirchhoff developed laws and theories fundamental to electrical engineering, heat capacity in chemical reactions, and the composition of light emission from incandescent objects. He even helped discover two new elements! In honor of what would have been his birthday, here is a look at Kirchhoff’s legacy.

Conserving and restoring art requires a balance between maintaining the quality of the work and respecting the artist’s initial creation. Advancing technologies now offer less invasive ways of analyzing artwork and bringing pieces back to their original condition. Since 2015 is the Year of Light, let’s explore how light can be used to conserve and restore paintings.

Reciprocating engines are used extensively for power generation in a variety of applications, most notably within the automobile industry. In the design process, it is important to ensure that all of the engine’s parts can withstand high stresses and loads in order to maximize the operational lifetime. Here, we analyze fatigue in an engine’s connecting rods.
