ABSTRACT:
Radar wave energy entering aircraft engine cavities is substantially disped by providing within such cavities surfaces having perturbations or dipoles which interact with the electromagnetic energy within the cavity interior, causing the reflected energy to be defocused or scattered over a broad range of angles thereby substantially lowering the radar cross section of the cavities.
