Abstract :
A simple formulation of absorbing boundary conditions with higher order approximation is proposed for the finite-difference time-domain (FD-TD) method. Although this formulation is based on the third order approximation of the one-way wave equations the authors have succeeded in reducing it to an equation in a form quite similar to the second order approximation.
