This book is a lucid, exhaustive, and in-depth presentation of the basic concepts in optics covering a wide area. It focuses on the inner integrity of these concepts, all relating to the classical and quantum versions of electromagnetic theory. It brings out the essential charm and elegance of physics.
It will be of substantial use to undergraduate and graduate students of physics taking up courses in optics.
What do the terms 'group velocity' and 'signal velocity' signify? What is meant by a negative refractive index? What is transformation optics? What is the eikonal theory of geometrical optics? What is the nature of stationarity in Fermat's principle? How is Gaussian optics related to linear optics? What is the dyadic theory of diffraction? What is a 4f correlator? What is mutual coherence? What is cavity quantum electrodynamics? What is parametric down conversion?
For these and a host of other basic questions in classical and modern optics, you will find it worthwhile to turn to the pages of this book.
