  1. Metamaterials

  2. Metamaterials Have a periodic material that has photonic or phononic properties. *Taken From 3.042 handout & Physics Worlds 2005 “Sound Ideas”

  3. Interference Lithography • Create photoresist film • Expose photoresist • Develop photoresist to create periodic structure

  4. Project Outline • Thick 1D structures (50-100 microns) • Variety of 2D structures (2-20 microns) • Phase mask creation • Thick 3D structures (50-100 microns) via phase mask interference lithography • Sol gel process to create 3D structures from other materials • Testing of photonic and mechanical properties

  5. Recent Progress Gained access to lithography laboratory Become certified in SEM and lithography Getting a working cost collector I.D.

  6. Recent Progress Created a 3D CAD model of a proposed periodic metamaterial Created a plastic 2D representation of a phase mask
