Abstract
We study the frequency selection problem for spiral waves in nematic liquid crystals in an imposed rotating magnetic field. We find that the frequency is selected due to local curvature of the spiral. The results are in excellent agreement with numerical simulations and consistent with experimental data. Possible generalizations to the case of multiarm spirals and anisotropic elastic constants are considered.
