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).
