We predict the spin-wave dynamics for the high-field phases of the frustrated antiferromagnet CuFeO2. After determining the appropriate magnetic ground state using a combination of Monte- Carlo simulations and variational methods for a two-dimensional triangular lattice, we evaluate the spin excitation frequencies and intensities using a rotational Holstein-Primakoff expansion for both the collinear and non-collinear states. These predictions will help experimentalists to identify the magnetic ground states of CuFeO2 with inelastic neutron scattering.
