Abstract

Security technologies have a big role in the development of the world of air transportation to prevent any plane accidents, including acts of terrorism. Currently, big worldwide airports have been taking advantage of the use of x-ray backscatter and millimeter-wave technology for metal detection in the human body. However, the implementation of this technology can cause ionization impact on the use of X-Ray backscatter technology and low accuracy result obtained from millimeter wave technology. The use of THz waves that occupy the electromagnetic spectrum between X-ray and millimeter-wave has been attractive to be an alternate solution for imaging applications. This paper discusses an imaging simulation of a metal object with THz waves radiation by using CST Microwave Studio. The considered radiation detection sensor is a bowtie antenna coupled with a bolometer structure that has the main resonant frequency in 1 THz. The bolometer has a resistivity of 8.75\times 10-6\Omega \mathrm{m}. The absorbed power in every bolometer will become a unit value component in an imaging result. Simulation and variation on the radiated frequencies have shown that the greater radiation coming to the metal object shows a lower diffraction effect. Further studies on a wider frequency band of the detected antenna are necessary for observing the antenna resonant and its effectiveness in absorbing irradiated power.
