9 2D Mapping (u=1.9mm, Hole Centered) 1mm 40mm 80mm -80mm GHz

10 Metamaterials for Curved Lenses
UCSD

11 Why Curved Lenses? Focuses Near Fields Super resolution imaging
Slabs (“Perfect Lens”) Curved Lenses Focuses Near Fields Super resolution imaging Super resolution illumination Focuses far fields Antennas Far field imaging

12 Why Metamaterials? Focusing performance Matching Compactness Weight

13 Focusing Performance Optical Aberration Coefficients
Gaussian optical formulas describe ideal point focusing. Aberration coefficients describe the deviation of a focus from an ideal point. Spherical Coma Astigmatism Field curvature Distortion

14 Optical Aberrations Coefficients
z x y z c200 spherical c110 coma c020 astigmatism c101 field curvature c011 distortion

15 Isotropic Spherical Coma Astigmatism Field curvature Distortion

16 Indefinite Spherical Coma Astigmatism Field curvature Distortion

17 Lens Aberration Comparison
