Abstract
We propose a multi-mode plasmonic surface acoustic wave (SAW) based sensor. Utilizing SAW, we have designed a dual-segment grating that can excite multi-mode surface plasmons. These modes behave differently by variation of target or environment refractive indices. This behavior can lead to a more accurate precision in sensing the target material by eliminating the interfering effect of fluid. Moreover, the proposed sensor is capable of determining the thickness of a known target.
