Abstract

A film includes a substrate having a planar surface attachable to a surface that transmits electromagnetic energy; and a photonic crystal structure formed in the planar substrate that alters the transmitted electromagnetic energy.

First claim

What is claimed is:

1. A film comprising:
a substrate having a planar surface attachable to a surface that transmits electromagnetic energy; and
a photonic crystal structure formed in the planar substrate that polarizes the transmitted electromagnetic energy.

2. The film of claim 1 , wherein the electromagnetic energy is optical energy.

3. The film of claim 1 , wherein the electromagnetic energy is microwave energy.

4. The film of claim 1 , wherein the electromagnetic energy is radio frequency energy.

5. The film of claim 1 , further comprising:
an adhesive layer adhered to the surface of the substrate; and
a backing layer releasably engaged to the adhesive layer.

6. A film comprising:
a substrate having a planar surface attachable to a surface that transmits electromagnetic energy; and
a photonic crystal structure formed in the planar substrate that alters the transmitted electromagnetic energy, wherein the photonic crystal structure attached to the surface forms a lens.

7. A film comprising:
a substrate having a planar surface attachable to a surface that transmits electromagnetic energy; and
a photonic crystal structure formed in the planar substrate that alters the transmitted electromagnetic energy, wherein the photonic crystal structure attached to the surface forms a lenslet array.

8. A film comprising:
a substrate having a planar surface attachable to a surface that transmits electromagnetic energy; and
a photonic crystal structure formed in the planar substrate that alters the transmitted electromagnetic energy, wherein the photonic crystal structure attached to the surface forms a beam shaper of more than one optical patterning element comprises a beam shaper.

9. A film comprising:
a substrate having a planar surface attachable to a surface that transmits electromagnetic energy; and
a photonic crystal structure formed in the planar substrate that alters the transmitted electromagnetic energy, wherein the photonic crystal structure attached to the surface forms more than one diffraction element.

10. The film of claim 9 , wherein the more than one diffraction element comprises a grating.

11. A film comprising:
a substrate having a planar surface attachable to a surface that transmits electromagnetic energy, wherein the substrate is flexible to conform to the surface that is nonplanar; and
a photonic crystal structure formed in the planar substrate that alters the transmitted electromagnetic energy.

12. The film of claim 11 , further comprising the surface that is a selected one of: (i) a lens; and (ii) a mirror.
