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.

EMI absorption/thermal conductivity/shock absorption all-in-one:
1. Versatile, multi-functional Alpha gel sheet
This versatile, RE series in Alpha Gel thermal conductive line are designed primarily to absorb electromagnetic noise, but it also works to effectively transfer heat.
With alminum sheet on one side, RE-100H shields electro magnetic noise as well.
Softness, inherent in Alpha gel,helps reduces impact/stress on devices.
2. Alpha gel brand:
Alpha gel is the umbrella brand for the patented, multifunctional silicone gel from Taica Corp. For over 20 years, its softness has established unique and distinct position in vibration isolation, shock absorption, thermal conductivity, and a comfortable feel in ways traditional solutions have fallen short.

Microwave Absorbers are increasingly being used to enhance shielding performance at higher frequencies. Laird Technologies offers a wide product range for the EMC design engineer.
Die-cut elastomers, foams, thermoplastics and custom solutions can aid in a wide variety of problems such as internal cavity resonances, antenna pattern shaping and high-frequency interference.
Where there’s a problem, Laird Technologies designs a solution.
Microwave-absorbing material technology is experiencing a growing and widespread interest among design engineers. As the name implies, microwave-absorbing materials are coatings whose electrical and/or magnetic
properties have been altered to allow absorption of microwave energy at discrete or broadband frequencies.Several techniques are used to achieve these properties.

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.

SAAFOxidant gas removal chemical media is designed to efficiently remove 99.5% of specific gaseous contaminants from the airstream. Target contaminants include sulfur dioxide, hydrogen sulfide, nitric oxide, formaldehyde, and lower molecular weight aldehydes and organic acids.
SAAFOxidant engineered media is composed of a combination of activated alumina and other binders. Potassium permanganate, an oxidizing agent, is applied to the media uniformly during pellet formation and is distributed throughout the pellet volume to promote optimal performance.
The SAAFOxidant chemisorptive process removes contaminant gases by adsorption, absorption and chemical reaction. In this process the gas is trapped and oxidized within the pellet, changing the gases into harmless solids while eliminating desorption. SAAFOxidant's engineering allows this to be an instantaneous, irreversible, and safe chemical reaction.
SAAFOxidant media is effective in commercial and industrial systems, withstanding velocities up to 500 FPM. The media operates at -4°F to 125°F (-20°C to 51°C) under 10- 95% relative humidity (RH).
