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.

Synthesizing Graphene with Chemical Vapor Deposition
Chemical vapor deposition is an attractive method for producing graphene, an ultrastrong and light polymer material. Researchers from University of Arkansas used simulation to study this process.

Ion Temperature in Inductively Coupled Plasmas (ICPs)
When modeling plasmas, your choice of ion temperature can affect your model results. We discuss the theoretical reasons behind this phenomenon using an inductively coupled plasma example.
