Design and Optimization of Gregorian-based Reflector Systems for THz Imaging System Optics
Mohammad Ghamsari, Mehdi Ahmadi-boroujeni, Saeed Babanejad
Application of reflector antenna configurations in designing the optical section of terahertz imaging systems has attracted great attention during recent years. Advantages of refle…
Improving the quality of active millimeter wave standoff imaging by incorporating the cross-polarized scattering
Seyedehzahra Shojaeian, Mehdi Ahmadi-Boroujeni, Shiva Hajitabarmarznaki
In this paper, we report a polarimetry-based THz imaging technique that highly benefits from backscatter data reflected from PEC hidden objects, considering the edge diffractions o…
A wide band low profile linear cross polarizer for millimeter wave applications
Shiva Hajitabarmarznaki, Mehdi Ahmadi-Boroujeni, Seyedeh Zahra Shojaeian +3
In this article, two wide band high-efficiency metasurface structures as a linear-cross polarizer in transmission mode based on asymmetric split-ring resonators (ASRR) are proposed…
