You know what a wave at the beach looks like. The water goes up and down, but the wave itself moves sideways toward the shore. The motion of the water is perpendicular to the direction the wave travels. That's a transverse wave.
Light works the same way. The electric field wiggles up and down. The magnetic field wiggles sideways. Both perpendicular to the direction the light travels. Every electromagnetic wave you've ever encountered (WiFi, radio, X-rays, the infrared heat from your coffee) does this. Electric field one way, magnetic field the other way, energy goes forward. That's all your textbook teaches.
Now imagine a slinky. You push one end. A compression travels along the slinky. The coils bunch up, then spread out, then bunch up again. The motion of the coils is in the SAME direction the wave travels. That's a longitudinal wave. Sound works like this. Air molecules compress and decompress along the direction the sound travels.
Here's the thing nobody told you: Maxwell's original equations allow for an electromagnetic version of the slinky wave. An electromagnetic wave where the electric field oscillates ALONG the direction of travel, not perpendicular to it. And this wave has no magnetic field at all.
Why does that matter? Because every technology that blocks electromagnetic waves (Faraday cages, metal shielding, the walls of a submarine) works by the same mechanism: the magnetic field of the wave induces electric currents in the conductor. Those currents resist the wave. That's the skin effect. That's why your WiFi dies behind a thick wall.
A wave with no magnetic field doesn't trigger that mechanism. No magnetic field means no induced currents. No induced currents means no skin effect. The barrier that blocks your WiFi doesn't interact with this wave type at all. It passes through. Not because it's stronger. Because the blocking mechanism doesn't apply.
Heaviside's simplification in 1884 removed this wave type from the equations. Not because anyone tested it and found it wasn't real. Because it complicated the math, and the simplified version was good enough for radio and light.
140 years later, four independent groups put it back. Same wave. Same math. Different formalisms. None cited each other. The wave was in the equations the whole time. Someone simplified it away.
That's the paper. That's the whole argument. The textbook uses 6 of 16 electromagnetic components. The other 10 describe this wave, and more.
