Figure 6. Narrowband absorption spectra of BMA with parameters: hZrN = 80 nm, L = 400 nm and W = 50 nm, obtained by varying Px (A) and Py (B) under vertical incidence while keeping the other periodic component equal to 900 nm with the inset curves of (0, ±1)-, (±1, 0)- , and (±1, ±1)-order RAs, variation of the ZrN thickness effects on the absorptivity and the FWHM for periods of 900 nm (C and D) and 1,000 nm (E and F). ZrN: Zirconium nitride; BMA: bifunctional metamaterial absorber; RA: Rayleigh Anomalie; FWHM: full width at half maximum.
