#### Simulation of scalar optical diffraction between arbitrarily oriented planes

(IEEE, 2004)

Scalar optical diffraction between arbitrarily oriented planes for monochromatic waves is analyzed and a simulator based on a discrete model is developed. The model is based directly on the Rayleigh-Sommerfeld diffraction ...

#### Integral action based Dirichlet boundary control of Burgers equation

(IEEE, 2003)

Modeling and boundary control for Burgers Equation is studied in this paper. Modeling has been done via processing of numerical observations through singular value decomposition with Galerkin projection. This results in a ...

#### 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 ...

#### Solutions of electromagnetics problems involving hundreds of millions of unknowns with parallel multilevel fast multipole algorithmt

(IEEE, 2009-06)

We present the solution of extremely large electromagnetics problems formulated with surface integral equations (SIEs) and discretized with hundreds of millions of unknowns. Scattering and radiation problems involving ...

#### PDE control of a rotating shear beam with boundary feedback

(IEEE, 2009-08)

We consider a flexible structure modeled as a shear beam which is clamped to a rigid body at one end and is free at the other end. The whole structure is free to rotate on the horizontal plane. We first model the system ...

#### Resonance lens antenna analysis for MM-wave applications

(IEEE, 2004-06)

We report what is to our knowledge the first accurate theoretical investigation of the electromagnetic behavior of 2-D elliptical lenses of finite wavelength-scale size. The role of internal resonances in the focal domain ...

#### Hybrid CFIE-EFIE solution of composite geometries with coexisting open and closed surfaces

(IEEE, 2005)

The combined-field integral equation (CFIE) is employed to formulate the electromagnetic scattering and radiation problems of composite geometries with coexisting open and closed conducting surfaces. Conventional formulations ...

#### On the accuracy of MFIE and CFIE in the solution of large electromagnetic scattering problems

(ESA Publications, 2006)

We present the linear-linear (LL) basis functions to improve the accuracy of the magnetic-field integral equation (MFIE) and the combined-field integral equation (CFIE) for three-dimensional electromagnetic scattering ...

#### Multilevel PO algorithm for non-uniform triangulations

(ESA Publications, 2006)

Fast physical optics (FPO) algorithm provides a speedup for computing the physical optics (PO) integral over complex bodies for a range of aspect angles and frequencies. In this paper, this algorithm is further developed ...

#### 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 ...
