A Finite-Difference Time-Domain Electromagnetic Solver in a Generalized Coordinate System

73 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1998.A new, finite-difference, time-domain method for the simulation of full-wave electromagnetic wave propogation in complex structures is developed. This method is simple and flexible; it allows for the simulation of transient wave propogation in a large class of practical structures. Boundary conditions are implemented for perfect and imperfect electrically conducting boundaries, perfect magnetically conducting boundaries, and absorbing boundaries. The method is validated with the aid of several different types of test cases. Two types of coaxial cables with helical breaks are simulated and the results are discussed.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD
