摘要：
This paper analyzes a multi-layered bowtie nano-antenna, consisting of alternate layers of silica (SiO2) and gold (Au). We show that the multi-layered structure can produce six times higher electric field enhancement than a purely gold bowtie antenna. The antennas may find applications in sensing (e.g., Surface Enhanced Raman Scattering) and imaging.
