A Low Complexity 2D Pattern Synthesis Algorithm for Cylindrical Array [PDF]
International Journal of Antennas and Propagation, 2013 This paper proposes a 2D pattern synthesis algorithm for cylindrical array. According to the geometric characteristic of cylinder, we can regard a cylindrical array as an equivalent linear array whose elements are identical circular subarrays. Therefore,

Terahertz scattering by subwavelength cylindrical arrays
Optics Express, 2011 We demonstrate the use of a full-wave electromagnetic field simulator to verify terahertz (THz) transmission-mode spectroscopic measurements of periodic arrays containing subwavelength cylindrical scatterers. Many existing THz scattering studies utilize analytical solutions, which were developed for a single scatterer.
