ECCOSORB VHP-NRL is a solid, pyramidal shaped, carbon loaded urethane foam absorber. The main application for this material is in the construction of anechoic chambers, or for covering test equipment, pedestals, etc... within anechoic chambers. It provides the highest broadband performance at both normal incidence and at wide incidence angles of all known absorbers. The NRL suffix refers to its compliance with the fire retardancy requirements of the U.S. Naval Research laboratory (NRL) test 8093. Eccosorb VHP is the preferred solution for Antenna , RCS and EW anechoic chambers because of excellent performance at microwave frequencies. While primarily designed for low forward scatter, i.e. angle of incidence equals angle of reflection, it offers favourable back scatter properties at off-normal incidence as well. It is thus well suited for use in all regions of anechoic chambers. It is available in a variety of thicknesses, giving the chamber designer the opportunity to choose grades appropriate for specific frequencies and incidence angles.
