Super Unit Cells in Aperture-Based Metamaterials

Figure 3

Types of unit cells considered; (a) basic (unperturbed) shape—simple rectangular apertures; (b) compound aperture (super unit cell) obtained by adding 30 nm × 30 nm square patches on each corner of the basic shape; (c) super cell obtained by adding four 60 nm × 60 nm squares; (d) supercell obtained by adding four 30 nm × 60 nm rectangles.
