Millimeter-Wave Gaussian-to-Flat-Top Beam Shaping Using a Single-Curvature Lens: A Novel Approach
Ehsan Imanbeygi, Mohammad Hossein Koohi Ghamsari, Mehdi Ahmadi-Boroujeni
This paper presents a novel method for converting the divergent Gaussian intensity distribution of a millimeter-wave source into a uniform (flat-top) distribution using a single cu…
Single-sided lens terahertz flat-top beam shaping in the Fresnel region
Ehsan Imanbeygi, Mohammad Hossein Koohi Ghamsari, Mehdi Ahmadi-Boroujeni +1
In this paper, a novel, to our knowledge, analytical approach is introduced for the design of a single-sided plano-convex lens (PCL) capable of terahertz (THz) flat-top beam shapin…
Confocal ellipsoidal displaced Gregorian structure for stand-off millimeter-wave imaging
Mohammad Hossein Koohi Ghamsari, Mehdi Ahmadi-Boroujeni
Reflective-based structures are favorable candidates as the optical section of millimeter-wave and terahertz (THz) stand-off imaging systems due to decreasing frequency-dependent l…
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…
