Figure 4. Effect of the phase compensating TiO2 overlay leading to both AR and ODR.

Figure 4

(a) Ag-TiO2-Ag nano-resonator incorporating a phase compensating overlay consisting of a 60-nm thick TiO2 film. (b) Transfer curves for the transmission/reflection spectra of the structure without and with the overlay. Total phase difference for the structure (c) without and (d) with the overlay. (e) Admittance diagram for the nano-resonator structure without and with the overlay.
