Nonlinear Metasurfaces to Mitigate High Power RF Surface Currents
Abstract
In this program, they will develop three specific ideas in nonlinear impedance surfaces outlined below: 1. They will extend work on self-tuning surfaces, which offer broadband absorption in a thin coating. This type of absorber is particularly effective against frequency-agile threats. 2. They will tailor their waveform-dependent absorber specifically for ultra-short pulses. This will be useful against impulse type sources such as “e-bombs” 3. They will develop a new transistor-based absorber, which they believe is likely to have faster and more tailorable response. This is the least mature of the three concepts, but it holds the potential for better performance than any passive nonlinear absorber.
