“…In addition, the resonant frequency of a bowtie antenna can be designed and tuned by appropriately modifying and scaling the bowtie geometry, such as its arm length, flare angle, and feed gap width. This enables the bowtie antenna to have various applications over a wide frequency range, including extremeultraviolet light generation [2], optical antennas [3,16,5], Terahertz-wave optoelectronics [17], mid-infrared plasmonic antennas and sensors [8,18], microwave radar [7], wireless communications [4,19], flexible RF devices [20], complex electromagnetic structures [21], and photonic detection of freespace electromagnetic waves [22][23][24].…”
