Funamentos todas las apps de lectura gratuitas de Kindle. Detalles del producto Tapa blanda Editor: Pearson India Idioma: The subject is difficult, but the author’s language makes it even worse. The book makes assumptions without telling the reader and very complex mathematical calculations are not worked out. A couple of weeks into the course, I found other textbook that were much clearer than Cheng’s.

It has many excercises,explained with very clearly.

This book is intended for a second course in the University. For example, first course is using the resnick book and the second course is using this. I though it was a hardcover, other than that it got home fast! The author’s language is convoluted, explanations are very brief, equations are thrown at your face with little explanation as to why or how they come into place, the worked examples are also quite convoluted and the author offers little explanation to solve them, theres little physics as to how EM actually works.

This seems to be the general norm when it comes to undergraduate engineering electromagnetics books, authors somehow feel they should condense explanations and math for engineering students and just throw in a bit of transmission line theory and antenna aplications, however EM is a very difficult subject to learn and condensing explanations and math actually makes things worse and harder to understand!

It is true that most engineers are not that interested in particles and such, which are covered in the traditional physics EM books, but that doesnt mean that we are only looking for a handbook of formulas and applications in an EM book! There are plenty of great EM books for engineers at the graduate level, like those by Pozar, Gonzalez, Balanis, Ramo, etc Its my conclusion that engineers should stick to the traditional physics EM books like the one by Griffiths to get a good understanding of EM theory, and then focus on engineering applications.

Cheng’s logical development of electromagnetics is indeed novel, but the only real way to appreciate it is to first have had a decently rigorous course on electromagnetism or have read another electromagnetics book. The reason why I say this is because at the onset of the book, Cheng puts forth his electromagnetic model, but there is absolutely almost no motivation for this model. It seems completely arbitrary, although elecrtomagnetismo does yield familiar results.

No basis for the model based on experiment is provided; therefore, I suggest that one first read a book that takes one through the historical path of development — leading from experiment to generalization.

Also, I have found a major error in the theory of the book. In Chapter 6 when Cheng is talking about potential functions, he correctly derives a formula for the curl of a potential function. Now, the basis of the book is that one can develop electromagnetics in an orderly fashion by specifying both the divergence and the curl of a vector. So, in order to fully develop the potential vector field, he says “we are still at liberty to choose the divergence of A. However, this is logically incorrect.

Just because one elechromagnetismo the curl of a vector field does not mean one is at liberty to state its divergence. Again, Cheng is completely arbitrary here and provides no basis for why he does this other than the fact that electromxgnetismo simplifies an equation. Many other books correctly deal with this matter — even on the introductory level. What really happens is that the Lorentz condition is a result of the relation between electromagnetics and the theory of relativity; when electromagnetic theory and relativity are combined, the Lorentz condition follows logically.

Sadiku’s Elements of Electromagnetics correctly states this, as do other texts. The reason why this is so important is that this is the crucial link between showing that electromagnetic fields that vary through time are represented as waves! This violates the nature of the book — that it should be logically consistent, orderly, and non-abrubt in its reasoning.

Finally, I would like to say that Cheng’s book Field and Wave Electromagnetics has the same downfall. However, I believe every serious student, engineer, and even scientist should read through Cheng’s Field and Wave Electromagnetics because it is more rigorous.

What Cheng has done is really interesting, but I simply cannot recommend this for any first time student. Electromagnetixmo, do not buy this book; buy his Field and Wave Electromagnetics because it is superior. Last and final note: Check out my review on his other text. Gana dinero con nosotros.
