FIG. 1.

Schematic of the charge polarization in two complementary polaritonic crystals before (a), and after the electric field is applied (b). Top is the crystal of spheres, and bottom the crystal of cavities.

FIG. 2.

Polaritonic band structure of the fcc crystal of dielectric spheres. Parameters: , , and . Inset: corresponding fragment of the band structure of a cubic crystal of perfect point-dipoles, obtained from Eq. (1). The dimensionless wave vector and frequency are and , respectively.

FIG. 3.

(a) Map of the z-component of the electric field of a wave propagating through the fcc crystal slab of spheres (parameters as in Fig. 2), at the frequency , for two different thicknesses of the slab. Color intensity corresponds to electric field amplitude at an instant of time, while color change indicates reversal of the field component direction. The light source is located at S, and the corresponding image at I. Inset shows a magnification of the slab, with sphere locations denoted by black circles. Colored figure available online. (b) Schematic of the light rays through corresponding slabs of a material with .
