This High Performance RF Absorber is wedge shaped and complements the conventional pyramidal shaped RF absorber. It is manufactured using the same material and processes.
The Wedge RF Absorber is designed primarily for use in chambers where RF energy is directed in a particular path such as energy propagation along a tapered chamber or in areas of the walls, floor and ceiling of a Free Space Chamber where the energy is directed to conventional pyramidal absorber on the back wall. Backscatter is significantly reduced or eliminated at these high angles of incidence.
The wedge absorber is produced with a base size of 610 mm x 610 mm and is available typically in the following depths:
152 mm, 203 mm, 305 mm and 457 mm
A feature of the Wedge RF Absorber is that its reflectivity performance at normal or near normal angles of incidence is similar or close to the standard RF absorber products. However it's wedge shape does make the product sensitive to polarisation. Consequently, the reflectivity values of Wedge RF absorber are 2 to 4 dB less than the equivalent depth Pyramidal RF Absorber.
