(color online) (a) Influence of height of cavity on absorption, the diameter of disk is , the periodicity of the disk is , the height of cavity is respectively 300 nm, 500 nm, 700 nm. (b) Same as panel (a) but the height of cavity is 500 nm, the periodicity of the disk is respectively , , . (c) Same as panel (a) but the periodicity of the disk is , the diameter of the disk is respectively , , .
