Research Institution
There is a current need for the passive protection of antenna apertures from electronic warfare (EW) and high power microwave (HPM) threats. Cornerstone Research Group Inc. (CRG) proposes to develop switchable electromagnetic windows that will passively respond to high power microwave threats. Switchable electromagnetic windows will have the ability to respond directly to the threat without an intermediate sensor system to activate the desired response. The windows will transmit electromagnetic energy in the normal state. If the incoming power density rises above a critical threshold, the material will automatically switch to reflect the incoming high power electromagnetic energy. When the threat has disappeared, the material will passively return to its normal operating state. These windows will allow for increased operational effectiveness, without subjecting sensitive equipment to damage from electronic warfare and high power threats. The extremely fast passive response time and lightweight nature of these windows will ensure maximum functionality and easy integration onto warfighter platforms. Development of this technology will enhance the state-of-the-art and contribute greatly to maintaining situational awareness both on and off the battlefield. BENEFIT: Operational Benefits: (1) Passive Protection from High Power Microwave Threats, (2) Blocks Only Threat Frequencies, (3) Extremely Fast Response Time, and (4) Lightweight. Commercial Applications: (1) Communications Systems and (2) Commercial Aircraft Electronics.
