The latter half of the book covers Rectangular Waveguides (TE/TM modes), Resonators, and Basic Antenna theory (Hertzian dipole, half-wave dipole). These are not just theoretical derivations; they include practical design parameters that are essential for GATE (Graduate Aptitude Test in Engineering) preparation.
Do not just chase the PDF; chase the intuition . As Shevgaonkar himself often says in his lectures: "Don't memorize the equation; live the field."
The Fresnel equations are derived with precise boundary matching. The concepts of Brewster angle (perfect polarization) and Critical angle (total internal reflection) are explained with real-world applications (fiber optics, radar).
For : Yes. The theory is comprehensive, and the question bank at the end of the PDF covers 90% of typical university papers.
: His research interests include fiber optic communication , photonics , antennas , and radio astronomy .
