1/ Description
AEMI manufactures a full line of wedge materials to complement our pyramidal absorbers. The wedge anechoic
performance matches those of the pyramids, except that they are polarization sensitive.
These materials are used to direct energy in a given path so that it can be effi ciently absorbed by large, high
performance materials.
