An efficient algorithm for wave scattering from two-dimensional lossy rough surfaces is proposed. It entails the use of a single magnetic field integral equation (SMFIE) in conjunction with multilevel sparse-matrix canonical-grid (MSMCG) method. The Rao-Wilton-Glisson (RWG) triangular discretization adopted to better model surface than pulse basis functions used well-established SMCG Using SMFIE formulation, only one unknown per interior edge mesh approximating required, and iterative...
Abstract A novel numerical scheme that employs quadratic B‐spline functions as temporal basis is proposed for solving time‐domain integral equations (TDIE) of electromagnetic scattering. Because the compact support these new functions, resulting solution efficient in terms memory usage and computation time. Numerical examples scattering by both conducting dielectric objects show also stable accurate. Compared with Lagrange interpolating same order, being complete to second yield a better...
Simulations of electromagnetic waves scattering from two-dimensional perfectly conducting random rough surfaces are performed using the method moment (MoM) and electric field integral equation (EFIE). Using wavelets as basis testing functions, resulting matrix is generally sparse after applying a threshold truncation. This property makes particularly useful in simulating large-scale problems, which reducing memory storage requirement CPU time crucial. In this paper, Gaussian few hundred...
The authors study simulations of 3D scattering and emission problems by using the sparse-matrix canonical grid (SMCG) method. near interactions among source points field are computed exact Green's function. In contrast, far fast Fourier transforms (FFTs) through a Taylor series expansion Green' s function about flat surface (z=O). can be repeatedly in iterative solution, or once stored depending on computer memory available, which will lead to low computation efficiency large storage...
The boresight error of an ablating radome is analyzed in this paper. A highly optimized program multilevel fast multipole algorithm (MLFMA) for volume integral equation (VIE) was developed to deal with the problem millions unknows. Results show that influences ablation on (BSE) and slope (BSES) could be very significant compared without ablation.
A Time Domain Integral Equation (TDIE) approach combined with Impedance Boundary Condition (IBC) for analysis of transient scattering by conductors coated absorbing material is developed. The IBC considered to be dependent on local incident direction and polarization property. Numerical results are compared the analytical MIE series solutions found in good agreements, demonstrating that proposed procedure stable, accurate efficient.

This paper is concerned with the stability and accuracy of time domain integral equation (TDIE) methods for analysis transient scattering by 3D dielectric objects. The PMCHW equations are adopted equivalent surface polarization magnetization as unknown sources. RWG spatial basis functions quadratic B-spline temporal employed. Parallel computation implemented handling large-size problems. Numerical examples show that present approach stable accurate.
Electromagnetic (EM) scattering from randomly rough surfaces has drawn an increasing attention due to its important applications in remote sensing of the ocean, soil and ice. The proposed wavelet approach is numerically exact, without limitations on RMS height slope. accuracy we want exclusively controlled by sparseness impedance matrix, which demonstrated order O(/spl beta/log/sub 2/N/sub x//N/sub x/). This conclusion based taking bistatic coefficient (BSC) predictions as simulation...
