📡 NASA documented the transmission of longitudinal electrostatic waves through solid dielectrics. It's on pages 404-407 of a 1999 conference publication. Nobody talks about it.
The Breakthrough Propulsion Physics (BPP) program at NASA Lewis Research Center documented signals propagating through glass and Plexiglas with LESS dispersion than through air. The waves carried no associated magnetic field. They were detected through closed wooden doors at distances of several meters.
In standard electrodynamics, electromagnetic waves always carry a magnetic field. Transverse EM waves can't do what these waves did. There is no mechanism in the standard theory for a longitudinal electric wave without B.
Extended Electrodynamics has a mechanism. The scalar-longitudinal mode predicted by the Stueckelberg Lagrangian carries a longitudinal E field and the scalar field C but no B field. Because it has no B, it doesn't induce eddy currents. No eddy currents means no skin-effect attenuation. It penetrates conductive barriers that block all standard EM.
The enhanced transmission through dielectrics is a specific prediction: a longitudinal mode coupling to the electric polarizability of the medium would experience reduced dispersion. Exactly the observed signature.
Hively's US Patent 9,306,527 reports consistent results: scalar-longitudinal wave transmission through Faraday enclosures, reception by monopolar antennas, 1/r² free-space attenuation instead of the 1/r characteristic of transverse radiation.
These results have not been independently replicated. But the mathematical framework is not speculative: EED uses the Stueckelberg Lagrangian structure, but its scalar field C is dynamical and irremovable, unlike the standard Stueckelberg compensating scalar which is pure gauge. Woodside proved the uniqueness of this extension.
Anomalous results documented by credible institutions, consistent with a theoretical framework that mainstream physics excludes by convention, not by proof. The Lorenz gauge doesn't just simplify equations. It renders an entire class of phenomena invisible to the formalism.
