Abstract :
A 44% reduction in the number of grid points required to solve the scalar wave equation using the finite-difference time-domain (FDTD) method has been made possible by a more accurate finite-difference approximation of the Laplace operator. Neither computation time, accuracy nor stability is compromised using the proposed algorithm
