Reflection of ultrashort pulses from the boundary of a Drude-Lorentz medium

Reflection of ultrashort pulses of electromagnetic radiation from the boundary between a vacuum and a Drude-Lorentz medium (a set of classical linear oscillators with a low concentration) is considered. For the case of two incident pulses, the possibility of interference quenching of reflected radiation is revealed. The quenching occurs when the pulse amplitudes satisfy a certain relation and the pulses follow with an appropriate time delay.
