Most textbooks on electromagnetics start with vector algebra and calculus, followed directly by Maxwell's equations. This can be an abrupt and jarring shift for students who have just completed their introductory courses on circuit theory, which deal mainly with scalar quantities like voltage and current.
Whether it is normal incidence or oblique incidence (Snell’s law), the book handles the mathematics of waves hitting boundaries. The concepts of standing wave ratio (SWR) and Brewster angle are explained with solved examples.
Most Western textbooks focus too heavily on theoretical physics or advanced numerical methods. Shevgaonkar’s book aligns perfectly with the curricula of the IITs, NITs, and state engineering colleges. It covers exactly what is needed for the UPSC and GATE examinations.
"I don't get it," Arjun groaned, rubbing his temples. "Maxwell’s equations look like ancient Sanskrit to me. Why are there so many curls and divergences?"
Detailed treatment of voltage and current on lines, including phase constants and attenuation constants.
A detailed treatment of finite transit time and wave behavior in physical conductors.
Exploration of how high-frequency currents crowd the surface of a conductor, a critical concept for RF and microwave design.
The book is also useful for professionals working in industries that rely on electromagnetic waves, such as telecommunications, medical imaging, and radar technology. The book's clear explanations, examples, and problems make it an excellent reference for anyone looking to learn about electromagnetic waves.
The heart of electromagnetics lies in Maxwell’s four equations. Prof. Shevgaonkar explains these equations in both differential and integral forms, bridging the gap between static fields and time-varying fields by introducing displacement current. 3. Plane Wave Propagation
"Electromagnetic Waves" by Prof. R.K. Shevgaonkar is a 2005 McGraw-Hill Education publication, widely regarded as a fundamental text for undergraduate engineering students specializing in Electronics and Communication. It employs a deductive, system-based approach to cover topics such as transmission lines, Maxwell's equations, and radiation, featuring numerous solved problems for academic preparation. Free NPTEL video lectures are available for study.
Shevgaonkar connects the theory of waves to physical structures. He covers:
Retarded potentials and field generation.
It transitions smoothly from basic vector calculus to advanced wave propagation.
Poorly scanned PDFs frequently distort integration signs, vector notations ( E⃗modified cap E with right arrow above B⃗modified cap B with right arrow above ), and subscripts, leading to confusion.
Many universities offer institutional access to digital libraries and e-book repositories (such as McGraw Hill Express Library or reference platforms).
