Abstract Optical sensors based on surface plasmon resonance are widely used in several applications. The structure to obtain the resulting polarization in the resonance of the surface plasmon in the Kretschmann configuration was investigated, a silver film acts as coating, in addition there is a dielectric layer which is deposited on the silver film, water is also used as substrate, using a source of λ = 633 nm. The resulting polarization change is shown according to the amplitudes- Ψ and the phases- Δ of the resulting wave associated with the ellipsometry function, on these functions there are remarkable points for each incident angle, which represent features such as suppressors, aligners and retarders.

棱镜结构表面极化等离子体激发下的反射偏振模式研究

摘要 基于表面等离子体共振的光学传感器被广泛应用于多种应用中。研究了在 Kretschmann 配置的表面等离子体共振中获得所得极化的结构，银膜充当涂层，此外还有沉积在银膜上的介电层，水也用作基材，使用 λ = 633 nm 的光源。根据与椭偏函数相关的所得波的振幅-Ψ 和相位-Δ 来显示所产生的偏振变化，在这些函数上，每个入射角都有显着的点，它们代表了诸如抑制器、对准器和延迟器之类的特征。
