- Polypropylene (pp) based microwave absorber
Series
The Polypropylene (pp) based microwave( electromagnetic wave) absorber is looking the same as our Polypropylene (pp) based hybrid pyramid absorber 3700 but this absorber is used on the high frequeny range. The absorber is designed for antenna measurement in anechoic rooms and
solution for Antenna Pattern Measurement (APM), Antenna Test Range (ATR), Radar Cross Section (RCS) and Electronic Warfare Test (EWT) chambers.
Depending on the different range of sizes, each size has its own reducing factor of electromagnetic waves. It can be used to cover up the low frequency band without the use of ferrite tiles.
It is possible to place the absorber on the foor. For this we've developed the Walkable floor for absorbers 3640-Floor series. When instralled it can be used to perform sVSWR tests in EMC chambers. Depening on the size of your shielded box it also can be used for high frequency range tests as well.
