商品描述

Computational Electromagnetics is a young and growing discipline, expanding as a result of the steadily increasing demand for software for the design and analysis of electrical devices. This book introduces three of the most popular numerical methods for simulating electromagnetic fields: the finite difference method, the finite element method and the method of moments. In particular it focuses on how these methods are used to obtain valid approximations to the solutions of Maxwell's equations, using, for example, "staggered grids" and "edge elements." The main goal of the book is to make the reader aware of different sources of errors in numerical computations, and also to provide the tools for assessing the accuracy of numerical methods and their solutions. To reach this goal, convergence analysis, extrapolation, von Neumann stability analysis, and dispersion analysis are introduced and used frequently throughout the book. Another major goal of the book is to provide students with enough practical understanding of the methods so they are able to write simple programs on their own. To achieve this, the book contains several MATLAB programs and detailed description of practical issues such as assembly of finite element matrices and handling of unstructured meshes. Finally, the book aims at making the students well-aware of the strengths and weaknesses of the different methods, so they can decide which method is best for each problem.

In this second edition, extensive computer projects are added as well as new material throughout.

Reviews of previous edition:

 "The well-written monograph is devoted to students at the undergraduate level, but is also useful for practising engineers." (Zentralblatt MATH, 2007)

商品描述(中文翻譯)

計算電磁學是一個年輕且不斷成長的學科,隨著對電氣設備設計和分析軟體需求的穩步增加而擴展。本書介紹了三種最受歡迎的數值方法來模擬電磁場:有限差分法、有限元素法和矩量法。特別是,它專注於這些方法如何用來獲得馬克士威方程的解的有效近似,例如使用「錯位網格」和「邊緣元素」。本書的主要目標是讓讀者意識到數值計算中不同的誤差來源,並提供評估數值方法及其解的準確性的工具。為了達成這個目標,本書經常引入並使用收斂分析、外推法、馮·諾依曼穩定性分析和色散分析。本書的另一個主要目標是讓學生對這些方法有足夠的實際理解,以便他們能夠獨立編寫簡單的程式。為了實現這一點,本書包含了幾個 MATLAB 程式以及有關有限元素矩陣組裝和處理非結構化網格等實際問題的詳細描述。最後,本書旨在讓學生充分了解不同方法的優缺點,以便他們能夠決定哪種方法最適合每個問題。

在這第二版中,增加了大量的計算機專案以及全書的新材料。

前一版的評價:
「這本寫得很好的專著專為本科生而作,但對於在職工程師也很有幫助。」(Zentralblatt MATH, 2007)
