Abstract
A novel approach, based on a theoretical formulation, is proposed for the analysis of finite-bandwidth signals in a lossy double-negative (DNG) slab. It adopts a signal expansion into Gaussian pulse functions, and provides an immediate approximate form of a modulated signal after the propagation in the dispersive medium. The accuracy and flexibility of the approach is proven studying the propagation of amplitude- and phase-modulated signals, and considering two different realizations of the DNG medium. © 2006 IEEE.File in questo prodotto:
