From: Broadband optical absorption by tunable Mie resonances in silicon nanocone arrays
Mie resonance and absorbance spectra of the Si nanocone arrays.
(a) Normalized scattering cross section of single Si nanocone (black) and Si nanocone array (red). (b) Relationship between reflectance (black) and normalized scattering cross section (red) of Si nanocone arrays. (c) Electric field distributions (|E|/|E0|) of Si nanocone arrays at different wavelength, the nanocone is 300 nm in height and 160 nm in base diameter. (d,e) Simulated absorbance spectra of Si nanocone arrays of various heights and base diameters. The arrows indicated the Mie resonance peaks.
