Classical Physical Interpretation and Engineering Applications of the Essence of Quantum Tunneling (Revised Edition)

The mainstream theory describes quantum tunneling as a special quantum behavior in which particles can cross energy barriers, relying on abstract concepts such as wave functions and probability clouds. It can only describe phenomena but cannot achieve precise control, lacking practical engineering guidance value. Abandoning fictional assumptions divorced from objective laws, this paper returns to the basic laws of classical physics and the real structure of matter, demonstrating that the essence of quantum tunneling is an equivalent phenomenon formed by the transmission of electromagnetic forces and relay replacement of electrons in a multi-layer atomic structure. It clarifies that particle collision angle and barrier thickness are the two core factors determining the tunneling success rate. This theory can not only restore the physical essence, but also directly guide practical engineering design and process optimization, realize the controllable utilization of tunneling effect, and has strong practicability and application value.
