We construct a modified Boulli iteration method for solving the quadratic matrix equation AX2+BX+C=0,where A,B and C are square matrices.This method is motivate
The inverse problem considered in this paper is to determine the shape and the impedance of an obstacle from a knowledge of the time-harmonic incident field and
There exists a strong connection between numerical methods for the integration of ordinary differential equations and optimization problems. In this paper, we t
For two-dimensional boundary integral equations of the first kind with logarithmic keels,the use of the conventional boundary element methods gives linear syste
Consider the diffraction of a time-harmonic wave incident upon a periodic chiral structure. The diffraction problem may be simplified to a two-dimensional one.
