Publisher's Synopsis
This book provides an introduction to the use of field theory (both in its classical and quantum formulation) to approach problems in Optics and Photonics, with specific emphasis on path integral methods. Starting with the familiar classical electrodynamics framework of Maxwell's equations and the light-matter interaction in the dipole approximation, the book slowly guides the reader through a journey that will touch several different aspects of Photonics and field theory, including quantisation, nonlinear optics, path integrals, and its application to problems in Photonics and 2D materials.
Key Features:
-
Comprehensive reference for field theoretical methods in Photonics.
-
Easily accessible introduction to theoretical physics models in Photonics.
-
Unifying view of classical and quantum properties of light-matter interaction.
-
A versatile platform to approach complex problems in Photonics.
-
Contains several worked examples of the primary calculations, both in the classical and quantum case, to help the reader getting familiar with the formalism, thus granting them access to the subject in an easy, beginner's friendly manner.
