### Abstract

Finite difference operators that are accurate and very spatially narrow may be constructed by optimizing the implicit 45° finite difference operator, analytically computing the required inverse operator for an inhomogeneous medium, and then truncating the resulting operator in a way which preserves accuracy and stability.
