A broadband absorber for absorbing a broad spectrum of incident microwave radiation is provided comprising a plurality of strips of inductive absorbing material having magnetic particles dispersed throughout an organic binder; the width, thickness, and composition of the strips being selected such that each strip absorbs a specific region of the microwave spectrum. The plurality of strips of absorbing material are supported by a substrate that is electrically conductive to microwave radiation. The substrate has a plurality of grooves and ridges in a repeating pattern, the grooves being of varying depths. A facing sheet, electrically transparent to microwave radiation, is provided for coupling the incident microwave radiation to the plurality of strips of inductive absorbing material.
