"This book prevents the reader from learning by heart and encourages him to meditate on the concepts, which are what remains and helps in individual study and research."
—Fabrizio Frezza, "La Sapienza" University of Rome, Italy
"While the importance of Electromagnetics as a foundation of the entire field of Electronic and Electrical Engineering to the education of our students is unquestionably great, most students say that this is the most challenging subject in the EE curriculum. This is primarily because it is incredibly abstract and mathematically intense. Professor Notaroš’ book provides a winning solution to this problem by teaching all electromagnetics topics completely based on conceptual understanding of the material and not on abstract, dry, and too complicated pure mathematical formalisms and derivations."
—Dragan Indjin, University of Leeds, United Kingdom
"I have many electromagnetics textbooks on my shelf. Although everyone has a different opinion on which one they like, to be honest they are mostly the same. This is the first E&M book I have seen in a long time that is truly `different’ from the others."
—Morris Cohen, Georgia Institute of Technology, Atlanta, Georgia, USA
"The main strength of this book is that it teaches students physics and tests their knowledge through conceptual questions."
—Guennadi Kouzaev, Norwegian University of Science and Technology, Trondheim, Norway
"For many students, a significant roadblock to their learning and studying the theory and applications of electromagnetics in the understanding of electromagnetics at the conceptual level. Students lose their motivation to delve into the mathematical details of the subject, once they cannot understand the concepts behind the equations. With this book, Professor Notaros, one of the most distinguished educators in the area, is making a significant contribution to help students overcome this roadblock and truly appreciate the beauty of the subject."
—Costas Sarris, University of Toronto, Canada
"As manifested by its title, Conceptual Electromagnetics, this book focuses on conceptual understanding of EM theory. It helps students to understand the physical meanings of equations. This is very important for students in their future work. One may forget the equations after graduation. However, the conceptual understanding will be kept in mind and guide people on how to design EM related devices and systems, e.g. antennas, PCBs, wireless energy transform systems, etc."
—Xiaoyan Xiong, The University of Hong Kong
"Conceptual Electromagnetics follows an innovative and unique approach, centered on conceptual questions. The book’s rich collection of conceptual questions, supported by clear illustrations, will certainly provide much appreciated inspiration as well as directly usable material to instructors, to enhance their teaching and assessment for electromagnetic field theory courses. To students this will be a valuable resource to assist them in gaining a thorough understanding of electromagnetic field theory. Students could work through these conceptual questions either individually or in groups and might well enjoy it."
—Matthys M. Botha, Stellenbosch University, South Africa
"This is a special book that includes plenty of conceptual questions that force students to think about what they are learning in electromagnetics courses. It is designed to fill the gap between the mathematical theory and the physical understanding. It is a good supplement for problem-based learning activities."
—Ozlem Ozgun, Hacettepe University, Ankara, Turkey
"This book is remarkable for its accuracy and rigor."
—Sandra Zivanovic, Louisiana Tech University, Ruston, Louisiana, USA
"Excellent and complete coverage for the undergraduate-level electromagnetics instruction. From what I see, the material represents a re-organized version of the text that I was already delighted to use, with the conceptual questions inserted within the text (instead of being separately available to the students on-line). This format, with the concepts introduced and immediately followed with a mini-quiz for the reader’s verification of understanding, is an ideal way for material coverage prior to problem-solving which can be done in class or tutorials."
—Milica Popovic, McGill University, Montreal, Québec, Canada
"Conceptual Electromagnetics is definitely different than a traditional undergraduate electromagnetics textbook…. Personally, I was happy to see a refreshing approach to undergraduate electromagnetics instruction; it is an interesting exercise and probably a step in the right direction. The general idea of the book is to introduce the difficult topics of electromagnetics to the readers in a conceptual manner."
—IEEE Antennas & Propagation Magazine, December 2017
"[Conceptual Electromagnetics] provides abundant opportunities for instructors to introduce innovative lec-tures, in-class and homework assign-ments, and tests (including those for online distance education and for students pursuing independent learning)."
