Abstract

Bolometer is a thermal detector that senses the change in the resistance of a metallic film caused by the temperature rise. The sensitivity of a bolometer is affected by the capability of the coupled antenna to absorb the THz radiation, thus optimally transferring the energy to the bolometer and raising its temperature. Aiming for the detection and imaging applications at 1 THz, a novel double-crossed bowtie antenna is proposed. The antenna is coupled to a Ti bolometer to absorb the incident THz radiation. A numerical study is performed based on the power dissipated in the bolometer. The results show that double-crossed bowtie could improve the absorption rate by 25 % compared to a conventional bowtie antenna when the incident radiation has dual polarization at the x- and y-axis. This research demonstrates the prospect of double-crossed bowtie antenna to enhance and tune THz absorption in bolometric-based detection with great potential in the application of real-time imaging.
