Near Field Properties and Plasmonic Effects of a Periodic Bowtie Antenna Array Embedded in a Substrate with Different Depths

Abstract—We numerically investigate the near field properties and plasmonic effects of a periodic bowtie antenna array which is embedded in a substrate with different depths by means of finite element method with three-dimensional calculations. The electromagnetic modes obtained from the embedding cases are quite different from that of air background case of the same size, resulting in an intensity enhancement and a redshift phenomenon. We find that the embedded depth of the bowtie antenna in a silica substrate is an important parameter which can influence the field enhancement and the position of peak resonant wavelengths. The near-field intensity becomes less intense and the spectrum of peak resonances red-shifted as the embedded depth is increased.

Index Terms—Bowtie antenna, finite element method, plasmonic effects, red-shifted.
