Analysis of Pulse Signal Reflection in Bragg-Type Layered Structures

Abstract

Analytical expressions for pulse signal reflected by traditional Bragg-type layered structures are obtained. The expressions for characteristic polynomial are calculated. The influence of the number of layers in the structure and contrast of permittivity on the form of pulse is studied. The analysis is done in the comparison with properties of the structure in frequency domain including behavior of zeros of frequency characteristic. The role of reverberations is revealed.
