Details Images
PFA is the most commonly used anechoic absorber material, with good normal incidence, oblique incidence, scattering and transmission attenuation performance in a wide frequency range.
When the ratio of material thickness to operating wavelength d/λ is 0.4, 1, 2.5 and 8, the reflectivity at normal incidence reaches -20, -30, -40 and -50dB.
The oblique incidence is within 30° of the incident angle, and the reflectivity does not change much.
At 60°, the reflectivity is 10-15dB higher than at normal incidence.Pyramid shape is neat, beautiful and clean, soft and bendable.Foam pyramid absorbers with a height of less than 100mm can be used to absorb clutter inside small anechoic boxes or electronic equipment.
When the ratio of material thickness to operating wavelength d/λ is 0.3 and 0.7, the reflectivity at normal incidence reaches about -17 and -30 dB.PFA is not suitable for outdoor use and has no requirements for substrates.
