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…
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…
