From: Sean Logan ➢ Tell me more about this "Longitudinal Wave"? Can you show me equations, or point me to papers? Last night, out of the blue, an engineer started telling me about this same thing. He showed me a pair of equations from his paper, but asked me not to publish them because they are export restricted.
There are dozens of papers out there due to Tesla worship. Many are bogus. Some are brilliant but speculative - I cannot say I understand the concept very well. Try: “Longitudinal Waves in Electromagnetism - Toward a Consistent Theory” Slobodan Nedic https://www.researchgate.net/publication/339747101_Longitudinal_Waves_in_Electromagnetism_Towards_Consistent_Framework_for_Tesla%27s_Energy_and_Information_Transmission_along_w_Energy_Harvesting This group has amended Maxwell’s equations and seems fairly believable. There are decent references at the end. There are also papers behind paywalls. And in Infinite Energy.
