Abstract: Based on the integration of a transmissive metasurface lens with the circuit analog absorber, the design of a microwave composite material with characteristics of both transmissive wavefront conversion and out-of-band radar cross-section reduction is proposed and examined. With the refraction tuned by gradient phase compensation, the lens consisting of sub-wavelength spaced layers of periodic inclusions exhibits a reciprocal conversion between planar and spherical wavefronts. Moreover, the responses of the lens at the lower side of the wavefront conversion band are used to construct a circuit analog absorption profile containing one lossy layer. By using an aperture-coupled microstrip patch antenna element as the primary feeding antenna, main lobe gain enhancement over a wide band is observed as a result of the wavefront conversion of the composite material. In comparison with the lens, the introduction of the circuit analog absorption profile produces radar cross-section reduction over the bandwidths of 130.68% and 155.11% for TE and TM polarizations, respectively. The full-wave simulation and experimental measurement demonstrate the enhanced radiation gain and reduced radar cross-section and illustrate the validity of the composite material design with integrated absorption and focusing.
