Adaptable Compressed Jaumann Absorber for Harsh and Dynamic Electromagnetic Environments
Abstract
Air Force combat vehicles are subjected to intense electronic warfare (EW) such as high-power microwave weapons, radars, and jammers. A long-term counteractive solution for a wide range of ever changing direct energy weapons is critical to the continued mission success of the aircraft. The electronic counter measure (ECM) solution however must not compromise the aerodynamics and weight characteristics of the radar cross section control armor. The PI will investigate the feasibility of realizing tunable compressed Jaumann absorber resistant to harsh electromagnetic environments. The PI will apply a recently demonstrated inter-coupling layer concept originally developed for frequency selective surface (FSS) filters and incorporate electronically controllable high-power resistant plasma-shells to establish the principle and the feasibility of the new technology for Air Force applications.The objective of this research is to strengthen future Air Force capabilities by developing ultracompact and light-weight electronically tunable microwave absorbers. When successful, the new multi-layered FSS based absorbers will deliver improved performance and functionality againstEW systems, while enabling more agile flight maneuverability. The overall thickness of the proposed multi-layered absorber can be simply adjusted to be much thinner or comparable to currently available state-of-the-art planar absorbers. It will support applications requiring extremely thin form factor, but if desired the same concept can also be applied for applications that require relatively thicker dimensions to enforce the structural rigidity. Furthermore, by integrating plasma-shells, the operational absorption spectral band can be controlled on demand to assure stable device operation subject to harsh and dynamic electromagnetic environments.
