Summary form only given. Many derivations of the MFIE make it appear that the half factor comes from an excluded region in the integral appearing in that equation. Since the excluded region yielded the half factor, a belief exists that it must not be double counted. As a result it erroneously appears that the integral should be viewed and numerically ...


Error analysis for the truncation of multipole expansion of vector Green's functions [EM scattering]

IEEE Microwave and Wireless Components Letters, 2001

One of the most important mathematical formulas in fast multipole algorithms (FMA) is the addition theorem. In the numerical implementation of the addition theorem, the infinite series should be truncated. In this paper, the number of terms needed for the scalar Green's function is derived, and the error analysis for the truncation error in the multipole expansion of the vector ...

  • MFIE limiting process and curvilinear computations

    Summary form only given. Many derivations of the MFIE make it appear that the half factor comes from an excluded region in the integral appearing in that equation. Since the excluded region yielded the half factor, a belief exists that it must not be double counted. As a result it erroneously appears that the integral should be viewed and numerically treated as a principal value integral. The principal value interpretation is theoretically correct but superfluous and can lead to an erroneous numerical treatment for curvilinear computational electromagnetics (CEM). A numerical treatment based on principal value singularity cancellation is shown to lead to large errors. The proper treatment recognizes that a non-cancelling integrable singularity procedure is needed. An alternate derivation of the MFIE is presented in which the principal value never appears.

  • Error analysis for the truncation of multipole expansion of vector Green's functions [EM scattering]

    One of the most important mathematical formulas in fast multipole algorithms (FMA) is the addition theorem. In the numerical implementation of the addition theorem, the infinite series should be truncated. In this paper, the number of terms needed for the scalar Green's function is derived, and the error analysis for the truncation error in the multipole expansion of the vector Green's functions is given. We have found that the error term in vector Green's functions is proportional to 1/R. If the scalar Green's function is truncated at the L-th term and the relative error is /spl epsiv/, then the relative error in the dyadic Green's function is /spl epsiv//4, if it is truncated at the (L+2)-th term. For the vector Green's function related to MFIE, the relative error is /spl epsiv//2 if it is truncated at the (L+1)-th term.

  • Least Square Method to Optimize the Coefficients of Complex Finite-Difference Space Stencils

    The numerical dispersion of the finite-difference time-domain methods can be lowered by using the complex space stencils. Properly adjusting the coefficients of the space stencils results in a further dispersion reduction. However, it is not trivial to determine the optimal values of the coefficients. This paper uses the least square method to optimize various finite-difference stencils. The method is validated by the numerical analysis

  • Electric Field Distribution Under Transmission Lines Dependent on Ground Surface

    This paper deals with the calculation of the electric field in the vicinity of a high-voltage overhead transmission line (TL). Since analytical formulas cannot be used to calculate the electric field in cases when the ground surface under a TL is not flat or when conducting bodies are located under it, we present the use of finite element method (FEM) for this purpose. The electric field distribution has been analyzed for two characteristic high- voltage TLs. A graphical comparison of the electric field strength <i>E</i> 1 m above ground surface is included.

  • Exact Near-Fields of the Dielectric Lenses for sub-mm Wave Receivers

    Focusing properties of a truncated elliptic dielectric cylinder with a piece- wise "super-elliptic" cross section taken as a 2-D model of a dielectric lens are studied for the plane wave illumination. The Muller integral-equation (IE) technique is used for the analysis of the scattering problem. This full-wave mathematically rigorous method guarantees uniqueness of the numerical solution for an arbitrary set of design and material parameters. To treat the singularities in the Green's functions and their derivatives in the discretization scheme we use analytical inversion of the canonical circular- cylinder counterpart of the problem. This procedure enables us to build a very efficient tool for CAD and optimization of the dielectric lenses. Numerical results for the near fields are presented and lens-focusing properties are studied for the E-polarization case.
