Applications
•
•
•
•
When placed within a cavity ECCOSORB
®
MCS has
proven to be very effective at dampening resonances
due to the absorbers high permittivity and permeability
as well as high loss values, which in turn reduces the
overall VSWR
ECCOSORB
®
MCS is designed for the suppression of
surface currents over a wide range of frequencies
Useful for the suppression of creeping waves and
reduction of cavity resonances in microwave modules.
ECCOSORB
®
MCS is also useful in reducing RF coupling
of antennas and microwave components
