摘要

在这项工作中，研究了基于双负折射率(DNG)材料的非常规红外表面等离子体共振SPR气体传感器结构的性能，并与使用单负折射率材料(SNG)的性能进行了比较。平面波分析表明，基于dng的结构比基于sng的结构性能提高了近8倍。研究比较了不同光斑大小的斜入射高斯光束作用下SNG和dng结构的性能。

DNG versus SNG-based IR SPR optical CO2 sensor performance evaluation under Gaussian beam excitation

In this work, the performance of a non-conventional IR Surface Plasmon Resonance SPR gas sensor structure based on the use of a double negative index (DNG) material is investigated and compared to the performance using a single negative material (SNG). Following plane wave analysis, DNG-based structure gives an enhanced performance almost eight times better than SNG-based structure. The performance of both SNG and DNG-based structures are studied and compared under the effect of oblique incident Gaussian beams with different spot sizes.
