Abstract :
Attention is focused on a new conformal FDTD method. The contour-path value of the electric field component can be obtained more accurately by the piecewise integration. Several examples are simulated to demonstrate the proposed method. Numerical results show that the PI-CFDTD method provides increased accuracy and stability over the conventional CFDTD method.
