Waveguides and periodic structures: Exact absorbing conditions on virtual boundaries in cross-section of regular waveguiding structures
2007 (English)In: Modeling and Analysis of Transient Processes in Open Resonant Structures: New Methods and Techniques, Springer-Verlag New York, 2007, 38-68 p.Chapter in book (Refereed)
In this and subsequent chapters, we discuss scalar and vector initial boundary-value model problems for two- and three-dimensional telegraphy andwave equations describing the scattering of electromagnetic waves by compact objects in unbounded domains Q of the spaces R2 and R3. The central problem arising in the course of the solution of such problems by finite-difference methods is caused by the progressively exp anding support of the scalar or vector function U (g, t), g ∈ Q, t ≥ 0, which determines the resulting field for the increasing observation times t. The analysis domain can be bounded by introducing anywhere in Q the artificial boundary L (see Fig. 1.1 C) and supplementing the original initial boundary value problem with the condition.
