  3. Utility for Image Processing and Analysis

  4. Calculations

  5. Current DefinitionwithPerforatedElectrode

  6. Current DefinitionwithPerforatedElectrode Distance between pillars = 108 nm will be changed to 125 nm (all the dimensions in nanometers) dpillar = 60 nm sample for simulation = 5 m x 5 m => npillars ≈ 2500
