  1. Close Up of Sample Top View Photonic Band Gap Negative Index Imaging Collaboration of the UCSD and MIT (Joannopoulos/Chen Groups) Data Summary of UCSD Group

  2. Special Testing Apparatus

  3. Transverse Field Profile Without Sample

  4. Illustration of Imaging with PBG

  5. Illustration of Difficulties With Near Field Imaging

  6. 40mm 6.0185 GHz 1mm 80mm -80mm 2D Mapping (u=1.9mm, Hole Centered)

  7. Metamaterials for Curved Lenses UCSD

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

  9. Why Metamaterials? • Focusing performance • Matching • Compactness • Weight

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