Analysis of radius-periodic cylindrical structures

The purpose of this communication is to present an analysis method for cylindrical structure which are periodic along their radii and are excited by a line source placed in the center. At first. we derive analytical formulas for the transmitted wave and the wave inside the structure of a single layer cylindrical structure, which allow to extract the characteristics of the cylindrical layer. Then we obtain the dispersion equation and the transmission coefficient of multiple layer periodic structures.
