Thesis (Ph.D.)--Northwestern University, 1990.

This dissertation explains the theoretical background of the contour finite difference time domain (CFDTD) algorithm, describes its implementation and presents validating results. Two and three dimensional electromagnetic scattering and interaction problems are modeled. The CFDTD algorithm is a generalization of the Maxwell curl equations based finite difference time domain (FDTD) algorithm. The basis of the CFDTD method is the finite integration and finite differentiation of the integral form of Ampere and Faraday laws.Subjects--Topical Terms:

520 $a This dissertation explains the theoretical background of the contour finite difference time domain (CFDTD) algorithm, describes its implementation and presents validating results. Two and three dimensional electromagnetic scattering and interaction problems are modeled. The CFDTD algorithm is a generalization of the Maxwell curl equations based finite difference time domain (FDTD) algorithm. The basis of the CFDTD method is the finite integration and finite differentiation of the integral form of Ampere and Faraday laws.
520 $a FDTD methods approximate object boundaries by a rectangular cell structure. The material parameters of each cell are constant throughout the cell and correspond to the actual material parameters of the object at the cell's center. Since each cell's material parameters are independently chosen, one can easily model complex objects. The modeling of boundaries between different materials necessarily follows the rectangular structure of the cells. Therefore curved surfaces are represented as stepped edges.
520 $a The CFDTD algorithm retains the flexibility of determining each cell's material parameters independently, while permitting the modeling of sub-cell geometrical features. The paths of the contour integral in this method can be deformed so as to conform to the boundaries of the object of interest. Thus the CFDTD method increases the accuracy with which one can represent objects.
