Optimizing the Design of Thermal Actuators for Use in Microsatellites
Microsatellites are replacing traditional large satellites in aerospace missions for gathering scientific data. Using simulation, we can optimize an important component of these devices.
Introduction to Plasma Modeling with Non-Maxwellian EEDFs
Modeling plasma that has a non-Maxwellian electron energy distribution function (EEDF) results in a catch-22. However, this issue can be overcome by building a simulation application.
Designing a Butler Matrix Beamforming Network with RF Modeling
Check out a tutorial model with implications in developing the 5G mobile network: Butler matrix beamforming networks, which can be combined with phased array antennas for wireless communication.
How to Analyze Laser Cavity Stability with Multiphysics Ray Tracing
If you’re looking for an in-depth example of multiphysics ray tracing, then check out this blog post about analyzing and predicting laser cavity stability in the COMSOL® software.
How Does the Choice of Ray-Tracing Algorithm Affect the Solution?
When performing a high-frequency optics simulation, do you use a sequential, nonsequential, or exact ray tracing algorithm? Learn how to choose to make the most of your solution.
Optimizing Microwave Furnaces for Solar-Grade Silicon Production
For silicon to be considered “solar grade”, it has to be 99.9999% pure. Therefore, microwave furnaces used to produce solar-grade silicon need to be optimized for quality and efficient output.
How to Calculate a Capacitance Matrix in COMSOL Multiphysics®
Calculating the capacitance between two conductors is simple, but adding more conductors to the mix (as is the case with touchscreens, transmission lines, and capacitive sensors) adds complexity.
How to Model the Optical Properties of Rough Surfaces
We develop a computational model for calculating the optical properties of rough surfaces, such as incident light on a dielectric material with random variations in height and thickness.
