THE REFLECTION OF LIMITED WAVE TRAINS AND IMPULSES,
Abstract
The reflection of a limited wave train and the reflection of an impulse from a plane boundary were investigated. When the beam or impulse struck the boundary at an angle close to the angle of total internal reflection, phenomena were encountered that were absent in the reflection of plane waves. Specifically studied were: (1) representation of a limited wave train in the form of superposition of plane waves, (2) the field of the reflected beam, (3) the displacement of the beam upon reflection, (4) the total internal reflection of a light beam, (5) reflection of ultrasonic beams, (6) the distribution of energy in the cross section of the reflected beam, (7) the energy flux in total internal reflection, and (8) reflection from an inhomogeneous medium. In the field of reflection of impulses, the general relations were examined, the law of conservation of impulses was studied, and the distortion of the impulse form in total internal reflection was considered.
