  • Equivalent dipole-moment method for electromagnetic scattering by dielectric bodies

    This paper presents an efficient method for the generation of MoM matrix based on the equivalent dipole-moment method for electromagnetic scattering by dielectric bodies. Based on the RWG basis function, the surface of the dielectric object is discretized into several triangular patches. Each RWG common edge element containing two triangular patches is regarded as a pair. The impedance matrix elements are calculated by conventional MoM when the pair of triangular patches of source point are not so far away from the field point, otherwise the electric and magnetic surface currents on the pair of triangular patches of source point can be equivalence as electric and magnetic dipole-moment, respectively, and all the rest impedance matrix elements are calculated by the equivalent dipole-moment method. Considering the boundary condition and PMCHW equation, the formula of impedance matrix elements is expressed. The equivalent dipole-moment method avoids the double integrates of the gradient of Green function and speeds up the forming of MoM matrix significantly. Numerical results show that it has less computation cost and high accuracy compared with MoM.

  • Moment method solution using expansion functions defined in an infinite domain for antenna problems

    The efficiency of the moment method when the expansion functions are defined in an infinite domain is investigated. It is shown that an efficient solution is obtained when the expansion functions exactly obey the known physical behavior of the fields. The age-old problem of a patch microstrip disk antenna excited by a probe at its center is used as a toy model. This antenna is solved by the moment method for which an electric field component is expanded outside the disk. Excellent agreement between the conventional moment solution based on expanding the surface current density on the disk and the present solution is obtained.

The aim of this work is first to introduce the application of wavelet in electromagnetic scattering, secondly a comparison of the two method of analysis is presented to show the limit of use of the asymptotic method an to emphasize on the fact that moment method is an exact method which is improved by the introduction of wavelet by reduction of both memory space and processing time, this is illustrated in this work.

  • Moment Method Using Fuzzy Basis Functions

    The paper introduces the use of fuzzy basis function (FBF) in moment method. Fuzzy logic systems (FLS) are universal function approximators, which can approximate any function to an arbitrary degree of accuracy. In the FLS, the user's insight can be taken into consideration easily and systematically resulting in a better approximation. Moreover, there are many choices in making a FLS depending on the problem. Options include the type of fuzzification, membership functions, composition, inference, and defuzzification, which show the richness of the FL technique. Many of the currently used basis functions in Moment Method could be viewed as special cases of fuzzy basis functions (FBF's). The method has been applied to the analysis of a parallel plate capacitor with holes to find the charge density on the plates and the capacitance as a result. The results are compared with conventional basis functions demonstrating the validity of the approach.

  • Comparing between current and field basis functions in moment method solutions

    The center fed disk antenna is used for comparing between the known moment method (MM) solution based on expanding the surface current density Jρ(ρ) on the disk, and the proposed MM expansion of the field component Eρ(ρ) outside the disk, on the disk plane. It is shown that for R <; λ, 3 current basis functions or 3 field basis functions are enough for excellent convergence of the solution. However, for R >; λ, more current basis functions are needed for getting a reasonable solution, while 3 field basis functions are enough for getting accurate solutions, where R is the radius of the disk and λ is the wavelength. CST software simulations are in good agreement with the MM results.

  • The effect of a nonlinear scattering gray medium on the radiative intensity by integral moment method

    The integral moment method is proposed to solve radiative intensity in nonlinear scattering gray medium. In this paper, this proposed method was to deal with the anisotropic scattering, emitting and absorbing media with different the Optical depth, orders and boundary conditions. This method was validated by the data from literature. The radiative intensities with high directional resolution at any point can be given by the present method. It is found that the scattering phase function has little effect on the radiative intensity for thin optical thickness, for example, 0.1. And there is the largest radiative intensity for the nonlinear scattering gray medium with the largest forward scattering capability, and the smallest one with the largest backward scattering capability at the top and bottom boundary.

  • Artificial Moment Method for Coordinated Control of Swarm System Formation

    To deal with the problem of coordinated control, an artificial moment method is presented for swarm system formation with overlapping information structure constraints. Each member of the swarm possesses itself proximity sensor and neighbor orientation sensor, and exchanges information with fixed neighbors. On the basis of formation regulations established by the system structure information, the proposed scheme makes each member coordinate its state and position with its neighbors according to the information provided by its sensors. Thus, the equilibrating stable swarm system formation is accomplished with the special information structure constraints

  • An equivalent dipole-moment method combined with multilevel adaptive cross approximation for PEC targets

    A novel hybrid method is proposed for solving electromagnetic scattering problem of three-dimensional perfect electric conducting (PEC) targets with electrically large size. In this work, we use the equivalent dipole-moment method (EDM) to accelerate the near region interactions in the multilevel adaptive cross approximation (MLACA) via solving the surface integral equation (SIE). Compared with the conventional MLACA, the time of near region interactions can be much reduced using Rao-Wilton-Glisson (RWG) basis functions. On the other hand, the proposed method can save memory requirement of the EDM from O(N<sup>2</sup>) to O(N<sup>4/3</sup> log N), where N is the number of unknowns. Numerical results are presented to validate the efficiency and accuracy of this method.

  • GPU accelerated higher-order moment method on NURBS model

    A novel higher-order moment method (HOMM) on NURBS (non-uniform rational B-splines) model enhanced by the graphics processing unit (GPU) programming technique is presented. The NURBS-HOMM can greatly reduce the number of unknowns and peak memory usage by using higher-order basis functions and larger NURBS patches. However, filling in the impedance matrix of the NURBS- HOMM always consumes long CPU time because of a four-dimensional integral consisting in each element. The GPU is a massively parallel processor and very suitable for compute-intensive and highly parallel computation. So, the GPU programming technique is applied to NURBS-HOMM to significantly reduce computation time. Numerical results show good efficiency of the proposed technique.
