Electromagnetic Field Theory By Dhananjayan May 2026

Dr. P. Dananjayan’s Electromagnetic Field Theory (often cited as Electromagnetic Theory

• Plane wave at normal and oblique incidence on a planar boundary; reflection and transmission coefficients (Fresnel equations).
• Brewster angle, critical angle, total internal reflection.
• Surface waves and guided wave conditions qualitatively.

1. Skip the first chapter (Vector Analysis) if you remember your math. Jump straight to Electrostatics (Coulomb's Law).
2. Mark the "Derivations" in the margin. In exams, they often ask "Derive the expression for..." directly from this book.
3. Use it alongside "EMF by Sadiku" for concepts. Use Sadiku to understand what a Divergence is; use Dhananjayan to solve problems on Divergence.
4. Don't ignore the Magnetostatics chapter. The Biot-Savart Law problems in this book are famously repeated in exams.

Students often prefer this book over more "dense" classics like Griffiths or Hayt for several reasons: electromagnetic field theory by dhananjayan

This is the heart of the subject. Dhananjayan slowly builds up to Maxwell’s equations: Plane wave at normal and oblique incidence on
