- Abstract
This current work presents the design and the experimental validation of an ultrathin a spiral Wire_coil wideband conformal metamaterial absorber. The proposed absorber is comprised of Wire_coil resonators on the upper side of the flexible substrate and a copper metal film on the lower side, which are separated by flexible PET (terephthalate). More than 90 percent of the frequency range from 16.5 GHz to 27.3 GHz was determined to be absorbed through testing. Due to its symmetrical form, the suggested absorber is indifferent to polarization. The absorber's unit cell is meant to be as small as possible with dimensions of 0.19λ0 x 0.19 λ0 (where λ0 is the wavelength at 16.5 GHz) .Using a parametric analysis and an equivalent circuit model, the absorber's wideband absorption mechanism was investigated further. Moreover, by varying the incidence angle up to 50 degrees, the bandwidth exhibits an effective absorption response for both TE and TM polarizations. Both simulation and experiment yield very similar results. Because of its simple design, the proposed absorber has potential properties for use in scientific and radio diffusion systems, offering outstanding performance.
