While books like David K. Cheng or William Hayt are popular, "Electromagnetic Waves" by R K Shevgaonkar is perfectly aligned with the syllabi of most Indian universities (VTU, Anna University, RGPV, AKTU, and IITs). Furthermore, the cost of the Indian edition is reasonable, making it accessible to a wide student base.
Professor R.K. Shevgaonkar’s "Electromagnetic Waves" provides a comprehensive, system-theoretic framework for understanding electromagnetics, focusing on high-frequency applications like 5G . The work emphasizes physical intuition and Maxwell's equations to cover topics including transmission lines, wave propagation, and antenna theory .

Professor R. K. Shevgaonkar, a distinguished academic and former Director of IIT Delhi, authored this book to bridge the often-intimidating gap between abstract mathematical physics and practical engineering application. While the market is flooded with international titles on the subject, Shevgaonkar’s book retains a cult-like status among students preparing for GATE, engineering services examinations, and university semesters. While books like David K
Electromagnetic fields are 3D phenomena printed on 2D paper. This often leads to confusion. Shevgaonkar uses distinct diagrams to map field lines. The illustrations regarding the polarization of waves and the standing wave patterns on transmission lines are particularly effective in aiding visualization. Professor R
One of the standout features of the writing style is the focus on "Why?" rather than just "How?". For instance, when discussing skin depth, the book doesn't just give the formula; it explains the physical phenomenon of current crowding toward the surface of a conductor at high frequencies. This depth of explanation prevents rote memorization and encourages genuine understanding.
In the pantheon of engineering education, certain textbooks transcend their primary function as mere reference materials to become the very bedrock of a student’s understanding. For generations of electrical, electronics, and communication engineering students in India and abroad, stands as one such seminal work.
To understand the value of this book, one must first appreciate the difficulty of the subject. Electromagnetic (EM) theory is notoriously difficult for undergraduate students. It requires a solid grasp of vector calculus—gradients, divergences, and curls—combined with the ability to visualize invisible fields propagating through space and time.
