Abandoning the de Broglie Matter‑Wave: Electrodynamic Origin of Quantum Wave‑Like Phenomena

The de Broglie matter‑wave hypothesis treats wave‑like behaviour as an intrinsic property of all microscopic particles. Based on the Charge‑Cluster Topology Hypothesis (CCTH), this paper points out that such postulate conflicts with multiple basic experimental facts: particle beams propagate in straight lines without spontaneous dispersion in disturbance‑free perfect vacuum; low‑velocity coherent particle beams do not produce spontaneous interference when intersecting in vacuum; electrically‑neutral particles and macroscopic neutral grains likewise exhibit no spontaneous wave‑like behaviour, in sharp contrast to light waves which can produce interference without gratings.This work argues that so‑called quantum wave‑like behaviour is not an intrinsic property of particles, but a statistical manifestation arising from deterministic electromagnetic interactions between charge‑packets and target nuclear charge‑clusters. Diffraction and interference patterns are superpositions of deflection landing positions of numerous independent events. Huygens secondary wave‑sources are equivalent mathematical descriptions of scattering centres rather than real expanding physical waves. The inverse proportional relation between equivalent wavelength and momentum originates from inertial impedance of electromagnetic coupling for high‑speed particles.This paper also challenges the ontological assumption that the uncertainty relation is a fundamental axiom of nature. Position‑momentum uncertainty is interpreted not as intrinsic fuzziness of individual particles, but as a statistical consequence of sensitive‑to‑initial‑conditions many‑body charge‑cluster dynamics plus electromagnetic perturbations introduced during detection. The mathematical formalism of quantum mechanics provides excellent phenomenological fitting for microscopic observations, yet does not directly represent underlying physical reality.Unified physical interpretations for relativistic mass‑increase, deep inelastic scattering and high‑energy particle showers are provided, together with several testable predictions. This manuscript presents a candidate‑hypothesis‑level argument. Quantum entanglement is outside the present framework; precise internal topology of nucleonic charge‑packets and quantitative treatment of gravitation remain unfinished. This preprint is derived from the CCTH theoretical series. It provides an alternative ontological interpretation for quantum wave‑like phenomena instead of negating the computational validity of quantum‑mechanical mathematics. Testable predictions are proposed. Quantum entanglement is explicitly marked as an unresolved boundary issue; precise nucleon internal topology and quantitative gravitation treatment remain unfinished.
