study the optical characteristics of bowtie nanoantenna integrations

The optical-plasmonic characteristics of different integrations of multiple bowtie antennas are investigated in this paper. fdtd simulation results demonstrate the realization of optical field coupling to the hybrid eight and sixteen gold triangles arrays respectively, which results in optical confining within the hybrid structures. localized optical field within the multiple subwavelength gap spaces can be utilized in a wide variety of applications such as optical lasers, optical sources, nonlinear optics study, data storage and etc.
