Quick Intro to Modeling RF and Microwave Heating

May 20, 2014

If you’ve attended a COMSOL webinar about an RF topic, you’ve probably seen our model of a waveguide with a bend. That’s because it illustrates microwave heating in an easy-to-understand way.

Intro Model: Studying the Signal Strength of RF Coils

May 9, 2014

Electronics designers need to ensure that RF coils contained within their devices can properly transmit information from a source to its destination. Electromagnetics simulation can help.
