Abstract
We present a new finite-difference scheme to study the scattering of sound in the time-domain. The scheme is based on a clever application of the split-operator technique previously employed in quantum mechanics to solve the time-dependent Schrödinger equation. This scheme has advantages in comparison with the usual finite-difference time-domain algorithms. Its main characteristics are: it has a precision of the order (Δt)3; it can work with non-homogeneous space-discretizations; and it verifies the energy conservation law.
