Abstract:Abstract.A temperature sensor based on surface-plasmon polariton in metal-insulator-metal waveguide and a half-open dynamic cavity with a movable silver granule driven by thermal expansion from a small cube of ethanol is proposed. Numerical simulations through finite-element method demonstrated that the temperature sensor can have a resolution as extremely fine as 0.412×10 -9 o C, The proposed design may find applications in micro-sensor chips for high-sensitivity measuring of temperature varying slowly in min… Show more
