Tunable Electromagnetic Chaff

Cornerstone Research Group Inc. (CRG) proposes to design and model tunable, metamaterial (MM) chaff using CRG"s electrically responsive material (ERM) as the tunable component of the chaff. CRG has invented a new class of ERMs that can change their electromagnetic properties when exposed to external stimuli. CRG will use ERMs to create tunable MM chaff that can be modified to change its electromagnetic response. This tunable chaff system will provide a number of benefits including: customized countermeasures, variable electromagnetic properties using a single MM design, and difficult to reverse engineer. This tunable chaff system will be designed to function with current chaff dispensing systems but will also open up a new design space for next-generation electromagnetic countermeasures and employment tactics.
