Requiring that the least action S 1⁄4 Lðq;q0;tÞdt be unchanged to first order in small virtual variations of qðtÞ, while holding the endpoints ðq1 ;t 1Þ and ðq2 ;t 2Þ fixed, leads to the Euler–Lagrange equation ...
Optics and photonics technologies are ubiquitous: they are responsible for the displays on smart phones and computing devices, optical fiber that carries the information in the internet, advanced precision manufacturing, enhanced defense ...
This new book presents an introduction to the essential elements of optics and photonics. Optics as a subject, has evolved dramatically in recent years, and is now an essential part...
The book thus provides a complete undergraduate course on optics in a single integrated text. The new edition has been completely updated and specific important changes include: New material on modern optics and photonics.
