An ear-to-ear propagation model based on geometrical theory of diffraction is presented. The model uses the creeping wave loss along the geodesic paths that connect the ears. It is the first model to investigate which geodesic paths that link the ear

The deterministic ear-to-ear on-body channel is modeled by the use of a number of elliptically shaped paths. The semi-major axes of the elliptically shaped paths are adjusted such that they trace the outline of the head. The path gain converges when
