Engineering Electromagnetic Fields and Waves 2nd Edition by Carl T. A. Johnk (PDF)

Description

Presents the introductory theory and applications of Maxwell’s equations to electromagnetic field problems. Unlike other texts, Maxwell’s equations and the associated vector mathematics are developed early in the work, allowing readers to apply them at the outset. Its unified treatment of coordinate systems saves time in developing the rules for vector manipulations in ways other than the rectangular coordinate system. The following chapters cover static and quasi-static electric and magnetic fields, wave reflection and transmission at plane boundaries, the Poynting power theorem, rectangular waveguide mode theory, transmission lines, and an introduction to the properties of linear antennas and aperture antennas. Includes an expanded set of problems, many of which extend the material developed in the chapters.

Reviews from Amazon users which were colected at the time this book was published on the website:

⭐Dr. Johnk was a spectacular Professor; I am honored to have known him and to have learned from him. His book is a great reference! My previous copy, which is autographed, is worn out, but kept safely as a treasure. I absolutely required another copy as a reference for my job. I was a little disappointed that this book was not a hardcover, but I’m thrilled to have another copy.

⭐The only fields book you should consider if you are learning it yourself. Johnk is the best teacher I ever encountered, and the book IS his class — everything is explained in detail. I never took a single note, as it is all in the book.If you read the book, you can do the problems. If you do the problems, you will know EM fields.This book is the summary of 35 years of teaching experience by one of the great teachers.

⭐I had the good fortune to attend 2 semesters of Johnk’s classes in college. Very thorough and concise, and his illustrations are clear. Buy this book if you want to have a firm grasp of the subject.

⭐I’m taking Adv. EM fields from the author now, and he is in his mid nineties and still teaching (very inspirational). The book is timeless…

⭐I bought this book becuase I had to. If you need it, buy it. If you do not need it, don’t. It’s really expensive! School is a scam

⭐I didn’t like the way the material delivered in this textbook but it has a valuable problems, if you get the solution manual it would be auesome for practising.

⭐Dr. Johnk was my professor for EE-3133, Electromagnetic Field Theory 1, at CU-Denver when I took this class years ago. Without even the slightest hesitation, he was the best teacher, at any class, at any level I ever had (Brian Atkinson, although not a PhD – not criticizing him, was also an amazing guy for Fields 2 and many other classes I had with him). There is a ridiculous level of detail in this book. I remember getting homework assignments back from Dr. Johnk where the papers had more red ink on them than my original handwritten work, and yet I’d get a 97% on it. You could feel a difference in the weight of the paper when handed back. I would number my homework problems like this: “1)” “2)”, etc. and he would finish the circle around each number in red ink as he corrected them all because that’s how he would number them. Very few PhDs with Dr. Johnk’s level of expertise would teach undergrad classes or even grade homework. But not Dr. Johnk. There are countless electrical engineers that earn a living today because of him. He was incredibly detailed in his work in class, something you’d have to experience to appreciate. He’d draw 3D field diagrams on the board in a half dozen colors of chalk that were pristine, absolute perfection. This was before cell phones had cameras, or I would have those drawings still to this day. The world lost a master when he died.

⭐This is an excellent book and should be considered the one to buy for this area of expertise. I would give it five stars if the book had the answers included…but it is dependent upon taking the class with a teacher’s help.Carl passed away earlier this year. He was a teacher with no equal.I took two of Carl Johnk’s undergrad classes and one graduate course (intro to antenna design) in the late 90s. An excellent teacher. Although I left the engineering field later in life, I took his teaching approach with me. He gave us detailed class handouts to accompany the homework assignments. As the semester progressed, the handouts became less detailed until he only gave hints on the harder problems. By the end of the second semester I was no longer a monkey cranking out diffy q’s, but a man who truly understood Greene’s Theorem (last section of his book). It was not only the hand-outs but the requirements for every homework (and test): clearly drawn diagrams and clearly written out explanations (not just number crunching) for *why* you got your answer. A master teacher who has no equal.
