# Gauge Permitting c Magnetic Vector and Instant Electric Scalar Potentials?

The Lorenz gauge requires c propagation of both scalar and vector potentials. The Coulomb gauge requires instant "propagation" of these potentials but is stated in such a way as to permit c propagation of the electromagnetic fields.

If recent experiments measuring the speed of the Coulomb interaction as instantaneously "propagating", such as "Measuring Propagation Speed of Coulomb Fields" were widely replicated and accepted, what might, say, a gauge used to calculate electromagnetic waves in the near and far fields (as is the Lorenz gauge now) look like?
