The text provides a systematic approach to electromagnetics, transitioning from static fields to dynamic, time-varying phenomena. Its structure typically includes:

Vector Analysis: Serves as the mathematical backbone, covering coordinate systems (Cartesian, cylindrical, spherical), vector calculus, and fundamental theorems like the Divergence Theorem and Stokes' Theorem.

Electrostatics: Analysis of electric fields in free space and dielectrics, Coulomb’s law, Gauss’s law, and solving for capacitance using Poisson’s and Laplace’s equations. electromagnetic field theory by dhananjayan

Magnetostatics: Detailed study of Biot-Savart’s law, Ampere’s circuital law, and magnetic boundary conditions.

Time-Varying Fields and Maxwell's Equations: This critical section bridges statics and dynamics, focusing on Faraday’s laws and the displacement current density that leads to the complete set of Maxwell’s Equations.

Electromagnetic Waves: Examination of uniform plane wave propagation in various media, including lossy dielectrics and good conductors. Educational Value for Students Electromagnetic Field Theory by Dr

Short review — Electromagnetic Field Theory by Dhananjayan

  • Scope: Introductory-to-intermediate textbook covering electrostatics, magnetostatics, time-varying fields, Maxwell’s equations, wave propagation, transmission lines, and basic radiation — suitable for undergraduate EE/ECE courses.
  • Strengths: Clear, concise explanations; many worked examples and end-of-chapter problems; practical emphasis with applied problems (transmission lines, waveguides). Good for students who prefer a compact, application-oriented treatment.
  • Weaknesses: Less rigorous/detailed than advanced EM texts (e.g., Jackson) — limited treatment of vector calculus proofs and theoretical depth; some chapters are terse and assume prior familiarity with calculus/linear algebra; referencing and notational consistency can be uneven in places.
  • Who it’s best for: Undergraduate students preparing for engineering exams, lab/practical courses, or as a supplementary resource for core EM classes. Not ideal as a sole reference for graduate-level theoretical work or advanced electromagnetic research.
  • Overall rating (engineering undergrad use): 3.5–4 / 5 — practical, readable, and problem-focused but not exhaustive in theory.

Is it "Helpful"? A Verdict.

| Scenario | Is the book helpful? | | :--- | :--- | | You have 3 days to prepare for university exams. | Yes. Just solve the last 5 years' questions marked in the book. | | You want to build a career in RF or Antenna Design. | No. You need Balanis or Pozar. This is just for passing. | | You struggle with derivations (Wave guides, etc.). | Yes. The step-by-step math is its strongest feature. | | You want intuitive understanding of EM fields. | No. Pair it with NPTEL video lectures (Prof. Harishankar Ramachandran). |

Overview

A.V. Dhananjayan’s Electromagnetic Field Theory is designed as a comprehensive textbook for undergraduate engineering students. In the curriculum of Electrical Engineering, Electromagnetic Field Theory (EMFT) is often considered a challenging subject due to its heavy reliance on vector calculus and abstract physical concepts. This book aims to bridge the gap between theoretical physics and practical engineering applications, simplifying complex mathematical derivations for the average student.
