The Internet of Space Takes Off with Advanced Antenna Designs
You’ve heard of the Internet of Things, but what about the Internet of Space, which change how we share information and communicate worldwide. A key aspect of this concept: antenna designs.
Analyzing an Electrodynamic Ion Funnel with COMSOL Multiphysics®
Quadrupole mass filters and ion mobility spectrometers are used to detect explosives, study complex biological molecules, and more. Ion funnels are an important component of these devices.
What Happens If I Use 2 Different Unit Systems in 1 Simulation?
Using 2 different unit systems for 1 project has led to historical disasters. Fortunately, you can use different unit systems in your simulation without issues by using the COMSOL® software.
How to Model Optical Anisotropic Media with COMSOL Multiphysics®
Erasmus Bartholinus first observed the optical effect of birefringence in 1669. Today, you can observe this effect with a specialized modeling approach for optical anisotropic media.
Should I Fillet the Geometry in My Electromagnetic Heating Analysis?
You want to analyze electromagnetic heating around sharp corners in your simulation. Do you round off the corners by adding a fillet? We go over cases where you should and shouldn’t do so.
Happy Birthday, Christian Doppler
The Doppler effect is observed both on Earth (such as the change in pitch when a siren passes you) and in space (such as the red shift of a planet). Learn about this phenomenon’s namesake.
