Preface

This text collects the material delivered in the course “Electromagnetic Fields” that I lectured starting from the academic year 2003–2004. This course was entitled with a value of five credits for the Science for Engineering Master Degree. The book was first written with the intention of producing a text of a small size (compared to the reference book by G. Gerosa and P. Lampariello [1]) that would retain most of the important application topics and, at the same time, a rigorous analytic treatment of all the arguments exposed. This last requirement was particularly important as the Master Degree in Science for Engineering aimed at providing all students with a solid and rigorous background in physics and mathematics. Over time I tried to improve the text usability, keeping the information selfconsistent and reporting all the fundamental intermediate steps in analytical computations. I now believe that, because of its conciseness, this book can be a very useful aid for all Electromagnetism students. My teaching experience makes me think that the objective was achieved, thanks both to an increasing lecturer effort and to a certain diligence required in the exam preparation, as students themselves recognized. I found it very useful to make the
