提出了一种具有双金贴片的等离子体结构，用于增强磁偶极子跃迁通过磁热区域的自发发射。在光频率下可以获得接近 2000 的 Purcell 因子，同时光发射器和谐振模式之间的空间和光谱失配的灵敏度较低。相关的共振可以从可见光到红外频率进行调节，从而能够使用等离子体结构有效控制禁戒跃迁。 (C) 2011 美国光学学会
A plasmonic structure with double gold patches is proposed for enhancing the spontaneous emission of a magnetic dipole transition through a magnetic hot area. A Purcell factor of nearly 2000 can be obtained at optical frequencies together with a low sensitivity in spatial and spectral mismatches between the light emitter and the resonance mode. The associated resonance can be tuned from the visible to the IR frequencies, enabling efficient control of forbidden transitions using plasmonic structures. (C) 2011 Optical Society of America
