Effective-mass anisotropy is incorporated into a self-consistent phenomenological theory of the high-frequency electrodynamic response of type-II superconductors in the mixed state. The theory accounts for two-fluid effects, including a possible anisotropic normal-fluid contribution, in addition to nonlocal vortex interaction. The approach, applicable to the modeling of a wide range of complex response functions, is illustrated in the calculation of the complex penetration depths and surface impedance for uniaxially anisotropic type-II superconductors.
