在共形变换的基础上，提出了一种设计等离子体纳米结构的一般策略，该结构能够有效地捕获宽带光谱上的光。表面等离子体模式向这些结构的奇异点传播，在那里群速度消失，能量积累，因此预期有相当大的增强和限制，因此当结构尺寸与波长相当时，也研究了辐射损失
On the basis of conformal transformation, a general strategy is proposed to design plasmonic nanostructures capable of an efficient harvesting of light over a broadband spectrum The surface plasmon modes propagate toward the singularity of these structures where the group velocity vanishes and energy accumulates A considerable held enhancement and confinement is thus expected Radiation losses are also investigated when the structure dimension becomes comparable to the wavelength
