Reduced radiation losses in electron beam excited propagating plasmons

Reduced radiation losses in electron beam excited propagating plasmons: Lei Wang, Wei Cai, Yinxiao Xiang, Xinzheng Zhang, Jingjun Xu, F. Javier García de Abajo
Except for heating losses in metal, propagating plasmons also suffer a lot from radiation losses. In this paper, electron beams are proposed as a way to excite higher-order, multipolar plasmons, which would otherwise not be excited by light, as a way to reduce radiation losses. Specifically, ...
