Abstract

This work presents a Physical Optics-based simulator for the analysis of THz imaging systems. The simulation starts by calculating the electromagnetic interactions inside the multireflector system and the incident field that the focusing system creates on the target under inspection. In a second step, the electric field that the modeled target scatters back to the system receiver, is also calculated. This allows to predict the imaging behavior of the system for different targets before manufacturing. The simulator results are validated by using measurements from an existing 300 GHz standoff imaging system. This contribution aims to help in the development of better imaging systems for security applications in the near future.
