  • Abstract
    A novel approach for implementing a stable nonorthogonal finite-difference time-domain algorithm is proposed. Instead of representing a vector field with its contravariant and covariant components, this approach only makes use of the covariant components to annihilate any unstable behaviour. The new algorithm is validated by numerical experiments.
