Paper Abstract

In order to provide a guide for the design and optimization of bowtie-shaped antenna arrays, their plasmonic properties have been experimentally and numerically investigated with emphasis on geometry and gap separation in THz frequencies. A stronger absorption, frequent red-shift and a higher Q-factor were observed in bowtie dimers, instead of the monomers. Based on the finite-element (FE) simulations using CST Microwave Studio, it was found that these resonant properties of the periodic bowtie particles can be further modulated by their geometric factors, including aspect ratio, area porosity as well as gap separation.
