More InfoQuote

ETS-Lindgren’s EHP Convoluted Absorber is designed to provide good reflectivity performance with low forward scattering characteristics at incident angles up to 60° from normal incidence at microwave and millimeter-wave frequency ranges.

The absorbers’ rippled or 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. ETS-Lindgren’s 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.
