Higher-order correction to the FDTD method based on the integral form of Maxwell’s equations

We propose a higher-order correction to the finite-difference time-domain (FDTD) method based on the integral form of Maxwell’s equations. We calculate the errors between the numerical and analytic solutions. Numerical solutions are obtained by the original method and our corrected FDTD method to show that the accuracy and reliability of our corrected FDTD method is superior to that of the original FDTD method.
