Abstract:

Article Preview

In this paper dipole type optical antenna and V type optical antenna are designed using gold and glass substrates, we compared their resonance properties by finite-difference time-domain (FDTD) method, calculated and analyzed their distribution and field enhancement effects contrastively. The results showed that in the same projected length, the resonant frequency of dipole type optical antenna was higher than the V type optical antenna, while the resonance enhancement factor was lower than the V type optical antenna. These have certain reference significance for researching characteristics of nanoantenna based on surface plasma.
