Abstract
The dynamics of wave propagation in media with negative index of refraction is analyzed through analytical calculations, simulations, and experiments. Using a free space setup, the transmission characteristics of two split ring resonator and strip wire left-handed media (LHM), designed for operation at -band frequencies (18–26 GHz), are measured. The first LHM, which is 3 unit cells long in the propagation direction, exhibits a maximum negative group delay of . The second LHM (4 unit cells long) exhibits a maximum negative group delay of . For both LHM the bandwidth of the negative group delay (and hence the negative group velocity) region was approximately 250 MHz.
