Metamaterial designs and inkjet printing have been demonstrated for many years but applications have been limited by available manufacturing processes resulting in poor performance at too high a cost. In addition, most inkjet printing of advanced electronic materials has been limited by material availability and equipment size limitations, typically less than 12 inches square. Only recently has inkjet printing been demonstrated to print large continuous rolls of electronic materials cost effectively. SI2 has been at the forefront of that development with its roll to roll Direct Write inkjet technology. In the Phase I effort, SI2 will design and manufacture a meter-sized electromagnetic metamaterial structure for use in a frequency band relevant to Navy applications. The Phase I feasibility study will form the basis of the Phase II where the scale of the metamaterial manufacturing will be increased and guided towards a more specific application defined during the Phase I effort. Benefits: In the Phase I effort, SI2 will show the feasibility of manufacturing meter-scale, multi-layer electromagnetic metamaterial structures via low cost Direct Write inkjet technology. The potential for low cost manufacturing will be shown through the successful Direct Write (DW) inkjet printing of the multiple layers that will be assembled into an electromagnetic metamaterial structure. SI2 anticipates that the Phase I project, base plus option, will result in a Technology Readiness Level (TRL) 2/3 for meter-scale, low cost, electromagnetic metamaterial structures for Navy applications.
