Objective Summary
The United States Air Force relies on yttrium iron garnet (YIG)-based microwave filters for critical radar, electronic warfare, and communications systems. These components require high-quality YIG epitaxial films in the 10–150 µm thickness range grown by liquid phase epitaxy (LPE). Domestic production capability for LPE-grown YIG films does not currently exist, and the entirety of this supply chain depends on foreign sources — representing a significant vulnerability to Air Force readiness, modernization programs, and long-term system sustainment.
The full objective, description, Phase I, II and III requirements and evaluation criteria are in the official topic on DSIP.
