Resumen
In this chapter, we present recent advances based on Fourier transformation techniques to
model dispersive UWB phenomena and far-field radiation from complex CRLH structures.
Section 2 first employs inverse Fourier transforms to study pulse propagation along this type of medium. Then, a Fourier transform approach is applied to the current which flows along the CRLH line, accurately retrieving the time-domain far-field radiation of the structure
[which behaves as a leaky-wave antenna, (LWA)]. The main advantages of the proposed
techniques are the easy treatment of complex CRLH structures, a deep insight into the physics of the phenomena, and an accurate and a fast computation, which avoids the time-consuming analysis required by completely numerical simulations.
