Electronic industry has dramatically advanced growth during the past few decades but still struggles to achieve the extreme specifications needed in many emerging applications that require ultra-wide band and high-speed signal transmission. The passive back bone of electronic system including interconnects and passive components have been identified as the main factors limiting system performance. Recently published technology roadmaps acknowledge the bandwidth limitation of interconnects and call for dramatic solutions to enable development of next generation electronic systems. In this proposal, an alternative solution for signaling in electronic systems by using bandpass interconnects instead of the conventional lowpass ones is proposed. These bandpass interconnects include substrate integrated waveguide-type structures, wireless interconnects that use antennas for launching and retrieving information and AC coupled interconnects that employ capacitive or inductive coupling for signal transfer. The bandpass feature of these interconnects brings new system capabilities such as wider bandwidth and lower transmission losses for the case of waveguides, and reduced delay and flexibility for the case of wireless interconnects. The AC coupled interconnects provide promising compact system integration capabilities. Each group opens new directions of innovative research for increasing data handling capacity of electronic systems. In this research program, system design considerations such as customizing driver and receiver blocks, dispersion compensation and signal and power integrity evaluations will be investigated. Development of enhanced passive components and integrated antennas, their miniaturization and signal integrity evaluations form another thrust of this research program. Electromagnetic bandgap structures continue to be a key element in engineering new components and power integrity solutions. The ultimate goal of this research is to address the design challenges in deployment of ultra wideband electronic systems.
