The nano Rectenna Project
Outline
2
• The motivation: solar energy harvesting using optical
nanoantennas
• The Dual Vivaldi antenna – geometry simulation results
• The fabrication process
• The measurements setup – using far field instead of
near field
• Design verification
• Future research
The nano Rectenna Project

• The energy from 1hr of sunlight striking the earth ( ) ~ 1 year of consumed energy worldwide ( in 2001*)
• Two main commercial technologies:
• Concentrating solar power (CSP) systems
• Photovoltaics (PV)
Both technologies at present have low efficiency !
