Overview:
Pyramidal Foam absorber can be utilized for the frequency range 30MHz to 110GHz. The factor determining the lowest useable frequency is the physical size of the pyramid. The larger the dimensions of the pyramid, the lower the frequency of operation. Due to the volume consumed within an anechoic enclosure when using large pyramidal material.
