Abstract :
We explore the use of a strictly microwave implementation of a familiar photonic structure, the chirped Bragg grating, as it can be employed as a dispersive filter for ultra-wideband (UWB) signals in the microwave domain. We demonstrate fully-electronic systems for real-time Fourier transformation, temporal imaging, and arbitrary pulse synthesis of UWB waveforms using so-called electromagnetic bandgap structures and we investigate their capabilities and limitations.
