The Research on Protective Layer Used in Surface Plasmon Wave Detector
介质保护膜在表面等离子体波探测器中的应用研究

In the detector based on surface plasmon wave resonance, the metal film contacts the detected material directly.A dielectric layer is coated on the metal film to protect it.In order to optimize the design of the surface plasmon detector, the requirements of parameters of the layer coated on the metal are gotten by analyzing the shift of resonance angle with the thickness and dielectric constant of the detected material.
