  • ETS-Lindgrens Convoluted Absorber is designed to provide good refectivity performance with low forward scattering characteristics at incident angles up to 60 from normal incidence at microwave and millimeter-wave frequency ranges.

    The absorber's convoluted front surface creates a gradual transition from free-space to loaded substrate, for absorption of electromagnetic energy. The convoluted geometry gives this absorber good RF absorption performance at wide angles of incidence, while maintaining robust longevity.

    Convoluted absorber is ideal for applications in treating antenna mechanical support structures, and/or metallic positioner devices as wrap-around absorber while testing antennas. It is also frequently used in small millimeter-wave anechoic chambers.
