Abstract :
This letter describes a new hybrid technique for enhancing the efficiency of the finite difference time domain method (FDTD) by incorporation with in Yee´s mesh a macromodel generated by an order reduction algorithm applied to the finite difference frequency domain (FDFD) wave equation defined on a higher resolution grid. This approach increases the accuracy of the calculations and reduces the overall simulation time.
