Modeling Beam Neutralization with a Charge Exchange Cell
A charge exchange cell refers to an area of high-density gas that is placed in the path of an ion beam. You can model a charge exchange cell to analyze its neutralization efficiency.
An Analysis of Caustic Surface Generation at the Vdara® Hotel
The Vdara® hotel on the Las Vegas strip has a unique crescent-shaped design that unfortunately contributed to the development of a caustic surface on the hotel’s pool deck.
Automatic Meshing for Electromagnetic Simulations
Ever struggle to mesh the infinite elements or perfectly matched layers in your electromagnetics simulations? Automatic meshing can help >>
Modeling Ray Propagation in a Newtonian Telescope System
Ray optics trivia: The Newtonian telescope, recognized as the earliest operating reflecting telescope, was developed in 1668. Today, simulation can be used to trace rays through this device.
Investigating LED Efficiency via Multiphysics Simulation
Ever wonder how efficient LED lighting is, compared to traditional florescent lighting? In this blog post, we demonstrate how to analyze LED efficiency with multiphysics modeling.
New Accumulators Boost Particle and Ray Tracing Functionality
Accumulators, a series of features available in the Particle Tracing Module, can be used to couple the results of a particle tracing simulation to other physics interfaces.
Modeling Thermally Induced Focal Shift in High-Powered Laser Systems
You can use the Ray Optics Module to create a fully self-consistent model of laser propagation that includes thermal and structural effects. Here, we take you through the process step by step.
Introducing the Ray Optics Module
COMSOL Multiphysics version 5.0 introduced an add-on module for electromagnetics modeling: the Ray Optics Module. It can be used to perform ray tracing and geometrical optics studies.
