Optical nanoantennas capable of converting external electromagnetic fields into confined energy and vice versa play a very important role in optical field manipulation. Among them, the bowtie antenna has received extensive attention from researchers in related fields because of its strong field localization and enhancement under the optical or electrical excitation, enabling a host of application scenarios.
