In-situ Large Area Fabrication of Metamaterials on Arbitrary Substrates Using Paint Process

Year: 2013

Type: article

Abstract: This paper proposes a novel method to make large area metamaterials on arbitrary planar hard or flexible substrates, in-situ.The method is based on painting the desired substrate with metallic and dielectric paints through a patterned stencil mask.We demonstrate this painting approach to fabricate ultrathin electromagnetic absorbers based on metamaterials at X-band frequencies (8-12 GHz) with paper-based stencils, silver ink and latex paint.Measurement results on absorber samples made with this process show absorption of 95%-99% in close agreement with simulation results.The proposed painting approach is a simple low cost additive manufacturing process that can be used to realize metamaterials, frequency selective surfaces, radar absorbers, camouflage screens, electromagnetic sensors and EMI protection devices.
