Absorption and shape transformation of pulse of electromagnetic radiation due to interaction with nanoparticle materials

We consider the resonant mechanism of high-frequency radiation absorption by nanoparticles possess either an electrical or a magnetic dipole momentum due to the resonant interaction of electromagnetic radiation with the natural vibration of nanoparticles bounded with carrier by different forces. The frequency range could be varied in wide limits by changing the force constant (e.g. by sintering nanoparticles with the carrier) and by nanoparticle sizes. Shape transformation of pulse of electromagnetic radiation due to reflection from surface is studied. We consider also influence of fluctuations of reflection coefficient on reflected pulse characteristics.
