The microwave camera can image at wavelengths which easily penetrate drywall and plywood.
In (A–C) an image is taken of a mannequin wrapped in aluminum foil in free-space, placed behind 12.7 mm thick dry-wall and behind 11.9 mm thick plywood. The mannequin is wrapped in foil in order to approximate the strong reflectivity of the human body23. The recovered 41 pixel by 41 pixel microwave-photographs are shown below each visible-light image (D–F).
