We compare the plasmonic response of two complementary structures to a scanning electron probe; a silver nanowire and a nanoslot in a silver film of comparable dimensions, desirable for their localized electromagnetic enhancement and enhanced optical transmission respectively. Through electron energy loss spectroscopy, multiple plasmonic resonant harmonics setup in both structures are resolved with inverted phase, in agreement with Babinet's principle, and of consequence in the design and fabrication of nanostructures.
我们将两种互补结构的等离激元响应与扫描电子探针进行比较；一种是银纳米线，另一种是尺寸相当的银膜中的纳米狭缝，分别因其局部电磁增强和增强的光传输而备受关注。通过电子能量损失谱，两种结构中建立的多个等离激元共振谐波以相反的相位被分辨出来，这与巴比涅原理一致，并且对纳米结构的设计和制造具有重要意义。
