Signals and energy move in the spaces, not in the traces.
When a principle of physics is accepted, it explains phenomena everywhere in the universe. The law of gravity works on matter, whether the masses are located on earth, in the sun and or among the stars. The law must transition at the atomic level where the particles must follow the laws of quantum physics. There may also be a transition when dimensions are those of the entire universe. For the world, we can sense there is only one law.
The laws I want to talk about are the basic laws of electricity. I am not referring to circuit theory laws as described by Kirchhoff or Ohm, but to the laws governing the electric and magnetic fields. These fields are fundamental to all electrical activity, whether the phenomenon is lightning, ESD, radar, antennas, sunlight, power generation, analog or digital circuitry. These laws are often called Maxwell’s equations.
