Theoretical study on wave-absorption properties of a structure with left- and right-handed materials
AbstractA wave-absorber model with air/left-handed medium/right-handed medium/metal structure is proposed. The wave-absorption properties of the structure are theoretically analyzed and numerically simulated. The structure’s parameters are optimized employing a genetic algorithm. The results show that under the conditions of that the wave is normally incident and the structure parameters are well matched, the peak values of the reflectivity can be reduced, the absorbing bandwidth can be broaden and an average reflectance of −12dB can be realized in the frequency range from 0.4GHz to 10GHz.
