We investigated the receiver functions in a horizontally-layered medium with arbitrary oriented hexagonally symmetric anisotropy, and discussed the phenomenon of shear-wave splitting and energy deviation in an anisotropic medium. The anisotropic structure yields patterns of receiver function amplitudes and arrival times on both the radial and transverse components that are a systematic function of source-receiver back azimuth. We also investigated the influence of varying anisotropy parameters, e. g.
