Abstract :
This paper presents the use of Terahertz (THz) SPR near-field sensor based on array of sub-wavelength metallic holes and Bull´s eye structure to characterize materials such as PMMA and those used in organic light emitting diode (OLED). The measurement results confirmed the theoretical SPR frequencies for metal-silicon mode and demonstrate a shift to 0.9211 THz from 0.9375 THz due to 2 μm of PMMA layer on the surface.
