A simple and efficient weak form of the well-conditioned electric-field integral equation

A simple and efficient weak form of the WEFIE is presented. It has been proved that the well-conditioned property of the WEFIE can be maintained in this weak form. Numerical experiments have demonstrated the accuracy and stability of the presented weak form of WEFIE-L(M), even at low frequencies. The effect of round-off errors to the accuracy has been eliminated and numerically validated at very low frequencies.
