We propose using a specially designed metal-multilayer-dielectric structure deposited on glass substrate to enhance the evanescent field and improve the sensitivity of the surface plasmon resonance sensor. The proposed structure supports both hybrid plasmonic transverse magnetic modes and conventional waveguide transverse electric modes. We show numerically the significant enhancement of the evanescent field and improvement of the sensitivity for the waveguide transverse electric mode.

我们建议使用一种沉积在玻璃基板上的特殊设计的金属 - 多层 - 电介质结构，以增强倏逝场并提高表面等离子体共振传感器的灵敏度。所提出的结构支持混合等离子体横向磁模式和传统的波导横向电模式。我们通过数值模拟展示了波导横向电模式下倏逝场的显著增强和灵敏度的提高。
