Electromagnetic Field Theory And Problems By Murthy Tvs Arun Pdf

Title: A Comprehensive Overview of "Electromagnetic Field Theory and Problems" by Murthy & T.V.S. Arun

1. Introduction

"Electromagnetic Field Theory and Problems" is a widely recognized textbook designed to cater to the needs of engineering students and competitive examination aspirants. Authored by T.V.S. Arun and Murthy, the book serves a dual purpose: it acts as a foundational text for undergraduate courses in Electrical and Electronics Engineering (EEE), Electronics and Communication Engineering (ECE), and related disciplines, while simultaneously functioning as a problem-solving manual for competitive exams like GATE, IES, and UPSC.

• Wave velocity $c = 1/\sqrt\mu_0 \epsilon_0$.
• Plane wave propagation: $\vecE(z,t) = E_0 \cos(\omega t - kz) \hata_x$, $\vecH = (E_0/\eta) \cos(...) \hata_y$, where $\eta = \sqrt\mu/\epsilon$ is the intrinsic impedance.
• Poynting vector ($\vecS = \vecE \times \vecH$) representing power flow.

Module 3: Magnetostatics (Static Magnetic Fields)

This section deals with currents that are steady (DC). Wave velocity $c = 1/\sqrt\mu_0 \epsilon_0$

1. Vector Analysis (Foundational: gradient, divergence, curl, Stokes’ and Gauss’ theorems)
2. Electrostatics (Coulomb’s law, electric field intensity, Gauss’s law, electric potential, conductors and dielectrics, boundary conditions)
3. Magnetostatics (Biot-Savart law, Ampere’s circuital law, magnetic flux density, vector potential, magnetization)
4. Time-Varying Fields (Faraday’s law, Lenz’s law, induced EMF, displacement current)
5. Maxwell’s Equations (Integral and differential forms, physical interpretation)
6. Electromagnetic Waves (Wave equation in free space and lossy media, Poynting vector, plane waves, polarization)
7. Transmission Lines (Line parameters, standing wave ratio, Smith chart basics—depending on edition)
8. Appendices (Formulas, coordinate systems, mathematical identities)

This cascading difficulty builds real intuition. Vector Analysis (Foundational: gradient

Time-Varying Fields & Maxwell’s Equations: A central focus on time-changing fields and the derivation/application of Maxwell's equations.

• Work through the wave equation derivation in free space and in a conductor.
• Practice problems on skin depth, impedance, and Poynting vector power flow.
• If your PDF includes transmission lines, learn the voltage/current wave equations—but note that a dedicated transmission lines book (e.g., Rizzi) might be better for deep coverage.

• Distributed parameters, characteristic impedance, propagation constant
• Smith chart basics, impedance matching, standing waves
