| Abstract | Metamaterials have unlocked a number of unique optical properties for manipulating the electric and magnetic dipole resonances have drawn much attention over the past decades. It has been recognized that a metamaterial could provide a new approach to excite electromagnetic behaviors leading to potential applications in the fields of sensing, energy, and information The low-loss conformal processing integration of multi-band wide-angle electromagnetic antireflection metamaterials, functional layers and radome is a challenging research. In this paper, a high-permeability metamaterial with similar electromagnetically induced transparency (EIT) characteristics is constructed around the metal split ring, and the equivalent dielectric constant and equivalent permeability of the split ring meta-unit are analyzed based on the equivalent medium parameter inversion model. Analyze the regulation mechanism of array structure parameters on electromagnetic characteristics. The research results show that this EIT wave-transmitting material has the characteristics of wide working frequency, high transmission rate, and insensitive to electromagnetic wave incident angle and polarization direction. In view of this, a multi-band broadband electromagnetic antireflection metamaterial with a multi-layer nested coupling structure (open resonant ring-chiral spiral ring-cross symmetrical structural unit) is designed, which is continuous in different polarized electromagnetic waves from 0 degrees to 80 degrees. Large-angle oblique incidence 11GHz, 15GHz, 33Ghz three-band high transmission rate, bandwidth up to 1.3GHz, 1.02GHz and 1.678GHz. |
