%X A new time-domain Green’s function approach is
used to characterize a composite right/left handed (CRLH) leakywave structure as a function of time under ultra-short modulated
pulse excitation. This analysis is efficiently performed in the far-field region for both, a single CRLH element and for an
array. Several novel broadband applications, such as a real-time spectrum analyzer (RTSA) (which exploits the unique frequencyspace
mapping conversion of the CRLH) or an instantaneous
radar scanning (based on the time-frequency relation of chirpmodulated
pulses), are presented and discussed. Full-wave simulations
and measurements are provided to validate the results.
The semi-analytical formulation developed is compact, flexible
and fast, avoiding stability conditions as in other completely
numerical time-domain methods.
