<p>A radar absorbing material comprising multiple layers integrated to form a thin, flexible, and lightweight structure. The material includes a substrate (12) having disposed thereon absorber elements that are resistively loaded to enable one to construct a device relatively small and thin size. The broadbanding of the device is carried out by multilayering concepts in which different size antenna patterns (D1 and D2) are multilayered with each layer designed to absorb frequencies in a specified range. The absorber elements are selected for their intrinsic impedance properties and preferably be polarization insensitive. These absorber elements are disposed in a random and preferably aperiodic pattern.</p> |
