Self-Dual Power Splitters for Wide-Scan, Wideband Phased Array Applications

Self-dual media (SDM) have been shown to enable the design of inherently reflection-less radiating elements for phased array applications with extreme scanning demands. As a natural continuation to this work, we lay here the foundations for a complete SDM-based feeding and beamforming network system in the form of SDM-based power splitters. The scope of this work includes simulations and optimization of the splitters in several forms, as well as a transition from a conventional microstrip to SDM.
