Frequently Asked Questions
When would you typically use Cho-Mute materials?
Inside a cavity for dampening cavity resonance in near field interference/challenges.
What’s the difference between reflection loss and insertion loss?
Reflection loss (expressed in decibels, dB) is the ratio of reflected power to incident power. In simple terms, it means the reduction of a signal after it has attenuated through an absorber and reflected back via a reflective surface behind the absorber. Insertion loss, also known as transmission loss, is the reduction in power of a signal as measured after it has passed through an absorber having no reflective surface behind it.
