我们通过实验证明了一种基于几种不同尺寸的纳米带天线阵列的红外宽带吸收器。宽带特性是由于这些纳米天线在不同波长处激发的磁响应的集体效应。通过操纵纳米带宽度的差异，测量的光谱清楚地验证了我们的设计，以扩大吸收带的目的。
We experimentally demonstrate an infrared broadband absorber based on an array of nanostrip antennas of several different sizes. The broadband property is due to the collective effect of magnetic responses excited by these nanoantennas at distinct wavelengths. By manipulating the differences of the nanostrip widths, the measured spectra clearly validate our design for the purpose of broadening the absorption band.
