Sommario/riassunto |
|
This book opens a new avenue to an engendering field of applied physics, located at the "crossing" of modern photonics, electromagnetics, acoustics and material science. It also highlights the concept of "non-locality", which proves to be not a special feature of quantum phenomena, but is shown to have an important counterpart in classical physics and its engineering applications too. Furthermore, it visualizes the physical results by means of simple analytical presentations, reduced sometimes to the elementary functions. |
