Abstract
The lattice dynamics of face-centered square and edge-centered square lattice structures is classically examined using the harmonic approximation between atoms. The dynamical matrices and dispersion relations for the two lattice structures are derived. The eigenfrequencies are presented numerically. At long wavelengths, the acoustic branches and corresponding group and phase velocities are obtained.
