A weatherproof version designated AEP-WP or AEW-WP is similar to the standard AEP and AEW respectively. The difference being that the absorber is manufactured from a special foam or covered with a rubberized cloth. The product designator of these materials is AEP-XX-WP. Where XX designates the absorber thickness in inches. The standard material base size is 2' x 2'

The broadband pyramidal absorber is manufactured in two basic geometrics, depending upon size and performance requirements; Conventional right pyramid and twisted pyramid.
The AEP-4 to AEP-48 absorbing materials are based upon a conventional pyramid having a square base with a uniform base thickness, tapered to a point.
The AEP-72 to AEP-96 absorbing materials are based upon a unique geometry with the peak twisted 45 degrees so that there are alternate peaks and valleys, increasing the performance and reducing the mismatch at the base transition.
This unique feature increases wide angle performance as well as increasing the mechanical support of the peak. This product configuration is also available in 36" and 48" sizes upon request.
The fabrication process differs with each of the two geometries. Both procedures have been established to ensure that complete impregnation with the dielectric lossy material and the fire retardant chemicals are achieved.
The standard material base size is 2' x 2'.

The broadband wedge materials have been used successfully in the design of tapered chambers as well as facilities which must have low wall reflections. AEMI manufactures a full line of wedge materials which fully complement our AEP series of compliment absorbers. The anechoic performance of the wedges match those of the pyramids with the only difference being that (due to the inherent shape of the wedge), they are polarization sensitive.
These materials are used to direct energy in a given path so that it may be efficiently absorbed by large, high performance materials which compose the facilities termination.
The company manufactures only NRL fire retardant versions of its broadband absorbers which meets the requirements of NRL. specifications 8093.
Standard material base size is 2' x 2' or 2' x 4' depending upon the application.

Advanced ElectroMagnetics, Inc. (AEMI), developed the Absorbing Wall Module, which can be used within the cavity to absorb interfering signals on a selective basis, in order to help reduce moding problems. Basic features include portability which by simple movement will change moding conditions with changing frequencies.
The Absorbing Wall Module also eliminates moding hot spots and resonances while providing good wide angle performance. The use of EM materials for the modules provide low frequency performance, which will accommodate MIL-STD 461/462 applications.
The wall module is constructed by applying absorber materials to 24 gauge sheet metal. This permits increased efficiency in absorbing characteristics and also allows the user to shield the test environment from personnel or equipment behind the wall modules.
