• This article describes the design and simulation of a novel Fresnel elliptical reflector that can assist emerging technologies in the field of millimeter-wave and terahertz security imaging. The analytical expressions that satisfy the corresponding amplitude and phase of each section are presented in a general manner. Two different Fresnel reflectors are designed, and their performance is compared with conventional reflectors using numerical simulations based on the Comsol and Feko software packages. The simulation results confirm the proper focusing of the Fresnel reflector at the desired frequency. Furthermore, the frequency behavior of the designed reflectors has been thoroughly investigated. This study provides valuable insights into the design and simulation of Fresnel reflectors, which can significantly enhance the performance of emerging technologies in the field of millimeter-wave and terahertz security imaging.
