Special features of the transmission of a train of electromagnetic waves across transparent plates

An investigation is reported of the special features of the temporal and spectral characteristics of radiation reflected from and transmitted by a plane-parallel plate when this radiation is in the form of a train of plane electromagnetic waves which is limited in space. Attention is drawn to the possibility of conversion of trains of electromagnetic waves into a sequence of shorter trains separated by distances equal to their length. Possible applications of such trains are considered.
