Design and analysis of slotted sectoral waveguide array antennas embedded in cylindrically stratified media
(IEEE, 2014-07)Slotted waveguide antennas are being widely used in military and commercial applications for many decades. Low cross-polarization, high power capacity, ease of fabrication in microwave bands, and the ability to form arrays ... -
Efficient analysis of large phased arrays using iterative MoM with DFT-based acceleration algorithm
(John Wiley & Sons, Inc., 2003)A discrete Fourier transform (DFT)-based iterative method of moments (IMoM) algorithm is developed to provide an O(Ntot) computational complexity and memory storages for the efficient analysis of electromagnetic ... -
Fast acceleration algorithm based on DFT expansion for the iterative MoM analysis of electromagnetic radiation/scattering from two-dimensional large phased arrays
(IEEE, 2002)An acceleration algorithm based on Discrete Fourier Transform (DFT) is developed to reduce the computational complexity and memory storages of iterative methods of moment (IMoM) solution to O(Ntot), where Ntot is the total ... -
Fast algorithm for scattering from planar arrays of conducting patches
(Institute of Electrical and Electronics Engineers, 1998-04)A direct (noniterative) algorithm for the solution of the electromagnetic scattering from three-dimensional planar arrays of conducting patches is developed. For an N-unknown problem, the computational complexity of this ... -
A new method for the prognosis of scan blindness angle in finite phased arrays of printed dipoles
(IEEE, 2011)Scan blindness phenomenon is studied for finite phased arrays of printed dipoles on grounded planar dielectric slabs. A new method for predicting the scan blindness angles using the average scan impedances of a subsection ... -
A parametric analysis of finite phased arrays of printed dipoles on large circular cylinders and comparisons with the planar case
(IEEE, 2004-06)A parametric study of finite phased arrays of printed dipoles on electrically large coated cylinders is performed using a spatial domain hybrid MoM/Green's function technique. Dipole currents and several performance metrics ... -
Phase-only beam synthesis by iterative semidefinite relaxations with rank refinement
(IEEE, 2013)In phased array antennas, by varying the complex element weights beam patterns with desired shapes can be synthesized and/or steered to desired directions. These complex weights can be implemented by using amplitude ...
