| Summary: | In this dissertation, a novel approach to modeling the scattered field of a periodic
corrugated cylinder, from an oblique incident planewave, is presented. The approach
utilizes radial waveguide approximations for fields within the corrugations, which are
point matched to approximated scattered fields outside of the corrugation to solve for the
expansion coefficients. The point matching is done with TMz and TEz modes
simultaneously, allowing for hybrid modes to exist.
The derivation of the fields and boundary conditions used are discussed in detail.
Axial and radial propagating modes for the scattered fields are derived and discussed.
Close treatment is given to field equations summation truncation and conversion to
matrix form, for numerical computing. A detailed account of the modeling approach
using Mathematica® and NCAlgebra for the noncommutative algebra, involved in
solving for the expansion coefficients, are also given. The modeling techniques offered provide a full description and prediction of the
scattered field of a periodic corrugated cylinder. The model is configured to approximate
a smooth cylinder, which is then compared against that of a textbook standard smooth
cylinder. The methodology and analysis applied in this research provide a solution for
computational electromagnetics, RF communications, Radar systems and the like, for the
design, development, and analysis of such systems. Through the rapid modeling
techniques developed in this research, early knowledge discovery can be made allowing
for better more effective decision making to be made early in the design and investigation
process of an RF project. === Includes bibliography. === Dissertation (Ph.D.)--Florida Atlantic University, 2017. === FAU Electronic Theses and Dissertations Collection
