Advanced length scaling method of optical nanoantennas

摘要

We demonstrate more advanced length scaling method of aluminum based nanoantennas using waveguide theory and well defined dielectric constant of metals in extremely high frequency such as visible to near-infrared regions (wavelengths from 400 nm to 3000 nm). To verify that our simulation for length scaling is effective in visible to near infrared regions, we fabricated dipole nanoantennas. Furthermore, it is found that experimental results for nanoantenna arrays support our model.
