Parallel Solution of Integral Equation-Based EM Problems in the Frequency Domain (Wiley Series in Microwave and Optical Engineering)

Summary of the Book

The book begins by introducing the readers to the fundamental concepts of integral equation formulations for electromagnetic analysis. The authors build a strong foundation by explaining the mathematical principles behind these formulations and their application to real-world issues such as scattering and radiation problems. Subsequently, the transition toward advanced numerical methods enables a practical approach to approximate solutions, specifically focusing on the moment method (MoM).

As the book progresses, emphasis is placed on the challenges of solving larger systems derived from integral equations. Here, the authors present parallel computing methods as an effective solution to combat constraints like memory and computation time. Various parallelization strategies, both for shared-memory and distributed-memory architectures, are discussed in depth. Techniques such as domain decomposition, parallel factorization, and preconditioning are explained with mathematical rigor and supported by implementation frameworks.

The authors also delve into the implementation of parallel algorithms on modern architectures, including multi-core CPUs and advanced GPU platforms, with key insights into managing scalability, load balancing, and communication overhead. Finally, the book concludes with applied case studies that showcase real-world examples of the effectiveness of parallel computing in solving problems related to EM wave scattering, antenna arrays, and other complex structures.
