Radar absorbent material (RAM) has electrical properties similar to
free space. When radar impacts radar absorbent material, the
energy acts as though it "sees" infinite free space instead
of a boundary. The absorbed electromagnetic energy is dissipated as
heat and very little energy is reflected.
The disadvantages of radar
absorbent material include additional weight, expense, heating problems and
aerodynamic drag (if applicable).
