Structural geometry and phase shift dispersion.

(a) Side view of the achromatic component designed for achromatic lens. The component includes 51 unit cells as shown in the inset. The parameters w, h and p represent the width of dielectric, length of the waveguide and period of the MIM unit cell, respectively. (b) Relative phase shift through MIM structure at different wavelength at varied slit width in theoretical calculation and numerical simulation. (c) Theoretical and numerical calculated at different wavelength at different slit width.
