摘要：A binary-structured metamaterial absorber (BMA) consisting of a low-permittivity dual-layer all-dielectric resonance surface (ADRS) and reflector was simulated and experimentally validated. Analyses of relative impedance, electric/magnetic field and power loss density indicated that the proposed BMA exhibits two absorption peaks at 14.65 GHz and 16.61 GHz, resulting from the magnetic and electrical responses of ADRS, respectively. The dependences of absorption properties on the dimensions of the ADRS and material parameters of the ADRS are discussed. It is concluded that the upper layer of the ADRS acts as an impedance-matching layer directly influencing the absorption intensity, while the bottom layer offers frequency selectivity in the 13–15 GHz range. The current design uses a low-permittivity ADRS, with simplified design and easy preparation and is notably different from conventional ternary-structured metamaterial absorbers based on a metallic resonance surface. The simplicity of the proposed BMA makes it a promising low-cost ambient temperature alternative to conventional metamaterial absorbers and could open up practical applications.
