Modeling and Analysis of Transient Processes in Open Resonant Structures [electronic resource] : New Methods and Techniques / by Yuriy K. Sirenko, Nataliya P. Yashina, Staffan Ström.

Numerical Analysis of Transient Processes: Fundamental Results of the Theory, Methods, and Problems -- Waveguides and Periodic Structures: Exact Absorbing Conditions on Virtual Boundaries in Cross-Section of Regular Waveguiding Structures -- Compact Inhomogeneities in Free Space: Virtual Coordinate Boundaries in Scalar and Vector Problems of Wave Scattering Theory -- The Simplest Modifications of the Exact ABCs Approach and the Associated Numerical Tests -- Transform Operators in Space of Signal’s Evolutionary Basis: A Time-Domain Analogue of the Generalized Scattering-Matrix Method -- Open Periodic Resonators and Waveguides: Novel Results in Electromagnetic Theory of Gratings -- Model Synthesis of Resonance Quasi-Optical Devices: Dispersive Open Resonators, Absorbing Coatings, and Pattern-Forming Structures.

The principal goal of the book is to describe new accurate and robust algorithms for open resonant structures with substantially increased efficiency. These algorithms allow the extraction of complete information with estimated accuracy concerning the scattering of transient electromagnetic waves by complex objects. The determination and visualization of the electromagnetic fields, developed for realistic models, simplify and significantly speed up the solution to a wide class of fundamental and applied problems of electromagnetic field theory. The book presents a systematic approach to the study of electromagnetic waves scattering which can be introduced in undergraduate/postgraduate education in theoretical and applied radiophysics and different advanced engineering courses on antenna and wave-guide technology. On a broader level, the book should be of interest to scientists in optics, computational physics and applied mathematics.
