Resonant Absorption: Does Material Absorb Wave Energy?

Thierry12 · May 5, 2009

When a wave propagates in a materiel (wave has same frequency as natural frequency of the material) there is attenuation. Is the energy absorbed by the materiel?

It could be. The light could also be scattered into a different direction.

Attenuation of waves in a collisionless plasma is known as Landau Attenuation or Landau Damping. There is a wikipedia article:
