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 ...
MLFMA solutions of transmission problems Involving realistic metamaterial walls
(IEEE, 2007-08)
We present the solution of multilayer metamaterial (MM) structures containing large numbers of unit cells, such as split-ring resonators. Integral-equation formulations of scattering problems are solved iteratively by ...
Analysis of cylindrically conformal antennas using closed-form Green's function representations
(IEEE, 2015-04)
Probe-fed microstrip patch antennas and slotted sectoral waveguide array antennas embedded in cylindrically stratified media are analyzed with a hybrid Method of Moments/Green's function technique, where closed-form Green's ...
Fast integral equation techniques for propagation problems
(IEEE, 2004-09)
In this paper, the Method of Moments (MoM) solution is achieved for scattering problems by using the stationary Spectrally Accelerated Forward-Backward method (FBSA) and the non-stationary Spectrally Accelerated BiConjugate ...
Improving the accuracy of the MFIE with the choice of basis functions
(IEEE, 2004-06)
The accuracy of the magnetic-field integral equation (MFIE) for the Method of Moments (MOM) and fast-multiple-method (FMM) solutions of the electromagnetic scattering problems modeled by abitrary planar triangulations is ...
Investigation of the inaccuracy of the MFIE discretized with the RWG basis functions
(IEEE, 2004-06)
The inaccuracy of the magnetic-field integral equation (MFIE) discretized with the Rao-Wilton-Glisson (RWG) basis functions is discussed. The electric-field integral equation (EFIE) gives accurate results with the usage ...
Efficient use of closed-form Green's functions for three-dimensional problems involving multilayered media
(IEEE, 1994-06)
With the use of casting the spatial domain Green's functions into closed forms approach, it was demonstrated that the computational efficiency of the method of moments (MoM) for the solution of the mixed potential integral ...
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 ...
