Extraordinary high spectral sensitivity in surface plasmon resonance sensor by multi-mode sensing scheme formeasuring the thickness of an adsorbed layer of specific refractive index

Abstract

In this paper surface plasmon resonance sensor is studied by using gold and silver in its structure respectively, also the possibility of extraordinary high spectral sensitivity by using multimode sensing scheme is being investigated in this sensor. It is shown that due to the extraordinary high spectral sensitivity of surface plasmon resonance sensor measuring adsorbate layer thickness could be done effectively
