Abstract
Embodiments include an anechoic chamber lined with absorber to absorb electromagnetic energy incident upon the absorber and reflector edge interfaces. The chamber comprises a reflector to reflect waves from a source to form a substantially plane wave field in a test zone within the chamber. In some embodiments, the outer periphery of the reflector extends to the interior walls, floor and ceiling of the chamber. The outer periphery of the reflector is embedded in the absorber in some embodiments.
