Influence of Spatial Correlation Function on Characteristics of Wideband Electromagnetic Wave Absorbers with Chaotic Surface
文献摘要:
Electromagnetic metasurface with chaos patterned surface could bring rich interaction modes contributing to fully disordered random motions in deterministic systems,which preform uncertainty,irreducibility and unpre-dictability.We investigate the influence of the correlation function(CF)properties of surface random patterns on the wave absorption performance.The complicated correlation function provides a fully developed random state,broadening the absorption bandwidth significantly and is helpful for reaching higher absorption rate.With the increasing number of peaks in the correlation function,the absorption band at-15 dB reflectivity widens significantly,band at-20dB reflectivity begins to emerge.As the first peak's distance from the original point in the CF is enlarged,the absorption trough is gradually formed and deepened to-35 dB level.The results give in-depth understanding of the relation between absorption behavior and controlling parameters including corre-lation,image information and foam spacer layer thickness.This high absorption absorber has great application potential in customizable radio communication compatibility device and anechoic testing chamber.
