As wireless, high-speed digital, and mixed-signal systems become more compact and integrated, electromagnetic interference (EMI) can easily degrade signal integrity, create spurious responses, and cause system-level malfunctions. Cavities inside enclosures, closely packed PCBs, and densely routed cables often generate standing waves, surface currents, and unwanted reflections that are difficult to eliminate with shielding alone.

WithWave’s microwave absorbers are designed to suppress radiated noise over a broad RF and microwave frequency range and to reduce surface currents and reflections in cavity resonances through high magnetic loss characteristics. Available in rubber sheet, flexible urethane foam, hard-foam (EPP), and liquid types, they can be applied to housings, test boxes, antenna chambers, and around critical components to improve EMC performance without major mechanical redesign. Thin, flexible, and easy to handle, these absorbers can be cut, formed, and bonded to fit complex geometries in real-world systems.
