An electromagnetic absorber assembly capable of minimizing reflectivity caused by reflected and diffracted waves within a test chamber is presented. The absorber assembly includes a plurality of first wedges and a plurality of second wedges disposed in a symmetrical arrangement so as to form a continuous and smoothly changing v-shaped pattern along one or more walls of an anechoic test chamber. Each wedge has a triangular-shaped first end and second end formed by a pair of side walls and a base wall. One second end of each first wedge contacts and covers one first end of each second wedge along a contact plane. First and second wedges are disposed at a first angle and a second angle, respectively, about the contact plane in a symmetrical arrangement. The assemblies described could be installed on a flat or shaped absorber base or wall to divert reflected and refracted fields away from a quiet zone. Interplay between the shaped absorber base or wall and intersecting wedges facilitates minimization of clutter and secondary scattering.
