ORBIT FR Pyramidal Absorbers - AEP Series - Manual (Page 2)

12
1/ Description
Broadband pyramidal absorber is manufactured
in two basic geometries, depending on size and
performance requirements:
• Conventional right pyramid
• Twisted pyramid
The AEP-4 to AEP-60 absorbers are a conventional
pyramid with a square base of uniform thickness, tapered
to a point.
2/ Increase wide angle performances with Twisted
Pyramid
The Twisted Pyramid shape increases wide angle perfor-
mance and the peak’s mechanical support.
The AEP-72 to AEP-96 absorbers are based on a
unique geometry that has the peak twisted at 45 degrees,
creating alternate peaks and valleys, which increases
performance and reduces mismatch at the base tran-
sition. This twisted confi guration is also available in
AEP-36, AEP-48 and AEP-60 upon request.
