基于电阻膜的宽频带超材料吸波体的设计
Design of a wide-band metamaterial absorber based on resistance films
摘要
Abstract
A wide-band,polarization-insensitive and wide-angle metamaterial absorber is presented,which is based on resistance films.A unit cell of the absorber consists of a hexagonal resistance film,a substrate and a metal backboard.Simulated reflectances and absorbances indicate that this absorber has a wide-band strong absorption for the incedent wave from 7.0 GHz to 27.5 GHz,indicating that electrocircuit resonances are more suited to realize a wide-band strong absorption than electromagnetic resonances.Simulated absorbances under different polarization angles and different incident angles show that this absorber is polarization-insensitive and angle-wide.Simulated influence of substrate and resistance film on the absorbance of the absorber indicates that there exist optimal values for the capacitance between the resistance film and the metal backboard and for the resistance of the resistance film,where electrocircuit resonances are strongest and the absorption band is widest.关键词
