In 2D fast multipole method for scattering problems, square quadrature rule is used to discretize the Bessel integral identity
for diagonal expansion of 2D Helmholtz kernel, and numerical integration error is introduced. Taking advantage of the relationship
between Euler-Maclaurin formula and trapezoidal quadrature rule, and the relationship between trapezoidal and square quadrature
rule, sharp computable bound with analytical form on the error of numerical integration of Bessel integral identity by square
quadrature rule is derived in this paper. Numerical experiments are presented at the end to demonstrate the accuracy of the
sharp computable bound on the numerical integration error. 相似文献
