本書序言

The revolution in wireless communications calls for a new focus in the electrical engineering curriculum. Stuart M. Wentworth fills that need with his new Applied Electromagnetics: A Transmission Lines First Approach. Incorporating the popular MATLAB program throughout, it features practical applications for wireless systems, transmission lines, waveguides (including optical fiber), antennas, and microwave systems. Designed for use in a one- or two-semester sequence at the junior and senior level, it offers students both detailed theoretical grounding and hands-on experience in harmony with today’s professional practice.

本書特色

MATLAB examples found throughout the book
Numerical simulation helps students understand theory
•MATLAB 2.3 shows when connecting wire must be treated as transmission line. The student can see WHY the T-Line model is required, rather than just accepting some minimum length criteria on faith.
•In MATLAB example 8.4, a movie is created showing the radiation pattern from a dipole antenna as its length changes.
Many homework problems draw on the MATLAB examples
Simulations can point out when ideal theory can be applied to actual situations
•In MATLAB problem 2.18, students are asked to compare the field from a segment of charge to the field from an infinite length line of charge. The problem is similar to MATLAB example 2.3, so the programming is not difficult. Students are able to see that theory for an unrealistic infinite line can be put into practice in some situations.
Example Problems
•Students see the detailed steps needed to solve typical problems
Drill Problems
•Simple problems reinforce problem solving concepts
•Students working through the drill problems will have an easier time with the end-of-chapter problems
Practical Applications
•Illustrates practical nature of electromagnetic theory to motivate students
•Applications include loudspeakers, laser printers, microwave ovens and magnetic levitated trains

本書序言

無線通訊的革命需要電機工程課程的新焦點。斯圖爾特·M·溫特沃斯(Stuart M. Wentworth)通過他的新書《應用電磁學:以傳輸線為先導的方法》填補了這一需求。該書在整本書中都使用了流行的MATLAB程式,並且涵蓋了無線系統、傳輸線、波導(包括光纖)、天線和微波系統的實際應用。該書設計用於大三和大四的一學期或兩學期課程,為學生提供了詳細的理論基礎和與當今專業實踐相協調的實踐經驗。

本書特色

全書中都有MATLAB示例
數值模擬幫助學生理解理論
- MATLAB 2.3顯示了當連接線必須被視為傳輸線時。學生可以看到為什麼需要T-Line模型,而不僅僅是基於某些最小長度標準的信任。
- 在MATLAB示例8.4中,創建了一個動畫,顯示了一個偶極天線的輻射圖案隨著其長度的變化。
許多作業問題都依賴於MATLAB示例
模擬可以指出理論可以應用於實際情況的時候
- 在MATLAB問題2.18中,要求學生比較一段電荷的場與無窮長電荷線的場。該問題類似於MATLAB示例2.3,因此編程並不困難。學生能夠看到理論對於不現實的無窮線在某些情況下可以實際應用。
示例問題
- 學生可以看到解決典型問題所需的詳細步驟
練習問題
- 簡單問題強化問題解決概念
- 通過練習問題的解答,學生在處理章末問題時會更容易
實際應用
- 以實際的電磁理論來激勵學生
- 應用包括揚聲器、雷射打印機、微波爐和磁懸浮列車
