Properties:
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 **0, **0, **0 and **0dB.
The
oblique incidence is within *0° of the incident angle, and
the reflectivity does not
change much.
At *0°,
the reflectivity is ****5dB higher than at normal
incidence.
Pyramid
shape is neat, beautiful and clean, soft and
bendable.
Foam
pyramid absorbers with a height of less than **0mm 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 **7 and **0 dB.
PFA is
not suitable for outdoor use and has no requirements for
substrates
