Interest in Metamaterials has been rising drastically in the recent years as they have been used in several optical and RF applications, from antennas to perfect lenses and pulsed power devices. Nevertheless, the time-behavior of metamaterials remains opaque and poorly understood.
In this research work, characterization of a metamaterial structure in time and frequency-domain was made through simulations and experiments. The structure consists in a series of edge-side coupled Split Ring Resonators (SRRs) in a below cutoff waveguide. A linear time invariant model of distributed elements has been elaborated as well in an attempt to approach the structure’s behavior. The comparison between simulations, measurements and model demonstrated agreement and confirmed qualitatively behavior that was previously observed in similar structures. The linear model constitutes a basis for further studies to understand metamaterial behavior or for the design of metamaterial with controlled characteristics.
