Local-Ether Wave Equation of Electric Field and Interferometry Experiments with Moving Medium and Path

Recently, we have presented the local-ether model, whereby the propagation of earthbound waves is supposed to be referred uniquely to a geostationary inertial frame. Further, in order to comply with this propagation model, the modified Lorentz force law is developed. Thereby, the corresponding wave equations of potentials and fields are derived in this investigation. It is shown that the local-ether wave equation of electric field can account for various precision interferometry experiments in a consistent way, including the one-way-link experiment with a geostationary fiber, the Sagnac rotating-loop experiment with a comoving or a geostationary dielectric medium, and Fizeau’s experiment with a moving dielectric medium in a geostationary interferometer. These experiments together then provide a support for the local-ether wave equation. Meanwhile, some other phenomena are predicted, which provide a means to test its validity.
