: Detailed PDF transcripts of Prof. Shevgaonkar’s NPTEL lectures on "Transmission Lines and EM Waves" are available for free through Digimat and NPTEL .
If you'd like, I can explain a (like the Wave Equation) or help you solve a Transmission Line problem using the Smith Chart. Electromagnetic Waves R K Shevgaonkar Pdf
: Includes fundamental Maxwell equations, wave propagation in free space, transmission lines, waveguides, and radiation. : Detailed PDF transcripts of Prof
: A significant portion is dedicated to wave propagation, examining polarization, phase velocity, and power flow through the Poynting vector . He then breaks it down into three regimes:
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.
Understanding how waves travel through restricted geometries is crucial for high-frequency design. Shevgaonkar provides a comprehensive analysis of rectangular and circular waveguides, as well as the transition into fiber optics. 5. Radiation and Antennas
