Abstract :
The Green´s function of the background medium is the kernel of the integral equation (IE), and it diverges when observation and source points coincide; this is the origin of difficulties in accurately computing the entries of the Method of Moments (MoM) matrix. The basic idea of this work is to eliminate the Green´s function singularity, without affecting the stability and the accuracy of the integrals, through a proper windowing of the employed Green´s function spectrum.
