Paper Abstract
Bow-tie nano-antennas are the kind of plasmonic structures that are widely used in optical applications to obtain strong
electric fields in a limited volume. Their capability to enhance the incident light can be greatly improved by constructing
these structures from several alternating metal/dielectric layers. Following this approach, we introduce and then analyze
the performance of a multilayered Au/SiO2 bow-tie nano-antenna in the finite-difference time-domain software. We show
that the gold/silica thickness ratio of 50% leads to the improvement of the electric field enhancement on almost 50%,
when compared to a monolithic gold device, which makes the proposed design attractive for various sensing applications.
