# Learn Electromagnetics with Principles Of Electromagnetics by Matthew N.O. Sadiku: What's New in the 4th Edition

## Principles Of Electromagnetics Sadiku 4th Edition: A Comprehensive Textbook for Engineering Students

Electromagnetics is a branch of physics that deals with electric and magnetic fields and their interactions with matter and radiation. It is a fundamental subject for engineering students who want to understand and design devices and systems that use electromagnetic phenomena, such as antennas, radars, wireless communications, optical fibers, lasers, MRI scanners, and more.

However, electromagnetics is also a challenging subject that requires a solid background in mathematics and physics, as well as a clear and intuitive grasp of abstract concepts and principles. That's why choosing a good textbook is essential for learning and mastering electromagnetics.

In this article, we will introduce you to one of the most popular and widely used textbooks on electromagnetics: Principles Of Electromagnetics by Matthew N.O. Sadiku. We will give you an overview of the author's background, the book's contents, features, benefits, comparison with other textbooks, and tips on how to use it effectively for learning and teaching.

## Introduction

Who is Matthew N.O. Sadiku?

Matthew N.O. Sadiku is a professor of electrical engineering at Prairie View A&M University in Texas. He has over 30 years of teaching and research experience in electromagnetics, signal processing, communication systems, numerical methods, and computer networks. He has authored or co-authored more than 500 publications, including over 20 books. He is a fellow of IEEE, a registered professional engineer, and an active member of several professional societies.

What are the main features and benefits of the 4th edition of his textbook?

The 4th edition of Principles Of Electromagnetics was published in 2009 by Oxford University Press. It is an international version that has been revised and updated to reflect the latest developments and trends in electromagnetics. Some of the main features and benefits of this edition are:

It covers both static and dynamic fields, as well as their applications in transmission lines, waveguides, antennas, microwave circuits, electromagnetic interference, electromagnetic compatibility, etc.

It uses a vectors-first approach that introduces vector analysis before scalar analysis, which helps students develop a better understanding of vector algebra, calculus, and coordinate systems.

It provides a balanced treatment of theory and practice, with clear explanations of physical concepts, mathematical derivations, worked examples, solved problems, review questions, exercises, computer projects, and MATLAB examples.

It includes a wealth of pedagogical aids, such as chapter objectives, summaries, key terms, formulas, figures, tables, graphs, references, appendices, and an index.

It comes with a companion website that offers online resources and supplements for students and instructors, such as lecture slides, solutions manual, test bank, animations, simulations, etc.
