Shevgaonkar uniquely highlights the flaw in Ampere's law for time-varying fields. He shows that for a charging capacitor, the conduction current ($J_c$) is zero between the plates, but the magnetic field exists. Thus, $\frac\partial D\partial t$ (displacement current density) must complete the circuit. This insight leads directly to Maxwell's equations.

To understand why this specific PDF is in high demand, let's compare it to three other giants:
| Feature | Shevgaonkar | Sadiku (Elements of EM) | Griffiths (Electrodynamics) | Jordan & Balmain | | :--- | :--- | :--- | :--- | :--- | | Level | Undergraduate (B.Tech) | Undergraduate | Intermediate/Graduate | Advanced Undergrad | | Math Rigor | High (Calculus heavy) | Medium | Very High (Vector Calculus focus) | High | | Practical Examples | Excellent (GATE focus) | Good (Numerical problems) | Low (Physics focus) | Excellent (RF focus) | | Waveguide Coverage | Moderate (Chapter 11) | Excellent (Detailed) | Minimal | Excellent (Detailed) | | Best For | Indian university exams & GATE | First course in EM | Physics majors | Communication engineers |
Conclusion: If you are an Indian engineering student preparing for competitive exams, Shevgaonkar is superior to Sadiku for problem-solving speed and superior to Griffiths for applied engineering context.
Shevgaonkar derives the intrinsic impedance $\eta = \sqrt\fracj\omega\mu\sigma + j\omega\epsilon$. He then breaks it down into three regimes: Good conductor ($\sigma \gg \omega\epsilon$) where $\eta \approx \sqrt\frac\omega\mu2\sigma(1+j)$, and Good dielectric ($\sigma \ll \omega\epsilon$) where $\eta \approx \sqrt\frac\mu\epsilon$. This table is often printed as a quick-reference sheet in good PDFs.
