Microwave Absorbers

WithWave’s Microwave Absorbers can suppress the radiation noise of electronic devices for a
wideband radio frequency range and effectively reduce surface current and surface reflection in
cavity resonant applications due to materials’ high magnetic loss characteristics.
In addition to the rubber sheet type, the absorber includes a flexible urethane foam type,
a hard-foam (EPP) type, and a liquid type, depending on the application.

These are made of a mixture of polymer resin and metal magnetic powder.
They are thin and flexible, excellent in workability, and easily bonded.
