Abstract :
A comparative study on different singularity extraction techniques of Electric Field Integral Equation (EFIE) is presented Three types of methods which are the Duffy transform, projection integration and the analytic integration are implemented and compared Numerical results show the differences in the efficiency, memory usage and the accuracy of three methods. Furthermore, the best choice of the different methods is recommended for dealing with singularity when mesh sizes are different.
