OBJECTIVE: Develop lightweight, extremely thin electromagnetic shielding capable of defending from 20MHz to 20GHz at a level of 48 dB or higher. Shielding must be suitable for hypersonic applications, to include thermal considerations.


DESCRIPTION: Hypersonic interceptors have multiple systems that utilize internal capacitors, batteries and power conditioning. All of these components give off electromagnetic interference (EMI) that can interact in unintended fashions. Hypersonic flight itself also is a large contributor of EMI, which can have unwanted effects on internal systems. Extremely thin and lightweight material that is capable of efficiently blocking this interference while contributing minimally to the mass or internal volume used is crucial for effective hypersonic capability.


PHASE I: Design and develop innovative solutions, materials, and/or concepts to implement electromagnetic interference protection for internal components during all stages of flight. The solution should contrive novel uses of contemporary technologies, utilize new innovative materials or capture key areas for new development.


PHASE II: Complete a detailed prototype design incorporating government performance requirements. Coordinate with the government during prototype design and development to ensure that the delivered products would be relevant to an ongoing missile defense architecture and data types and structures.


PHASE III DUAL USE APPLICATIONS: Scale-up the capability from the prototype utilizing the new technologies developed in Phase II into a mature, full scale, fieldable capability. Work with missile defense integrators to integrate the technology into a missile defense system level test-bed and test in a relevant environment.
