Abstract :
We apply smooth local cosine (SLC) functions to integral equations to solve thin-wire scattering and radiation problems. Numerical examples of a thin-wire scatterer and antenna are presented. The results are compared with those obtained by using the standard pulse-based MoM. It is noticed that the use of the fast discrete cosine transform DCT-IV can drastically reduce computation time and increase the accuracy of numerical calculations.
