A Study on the Microscopic Mechanism of Dielectric Electromagnetic Effects Based on the Theory of Existence Field

Traditional electromagnetism quantifies the modulation of electromagnetic fields by media through permittivity (ε) and permeability (μ), yet there remain points worthy of discussion in the explanation of the microscopic mechanism, such as the understanding of vacuum attributes and the essence of the action mechanism. The Theory of Existence Field proposes that fundamental physical quantities (charge/mass) possess an inherent property of diffusing their own physical information into space, and the resulting "existence field" serves as the carrier of physical interaction. Based on the Theory of Existence Field and combined with the Unified Theory of Atomic and Molecular Structure (where the spatial configuration of electron orbitals determines atomic magnetic moment), this paper systematically deduces the microscopic mechanisms of dielectric polarization and magnetization. The research elucidates that the essence of dielectric electromagnetic effects is that an external source existence field transmits physical information to the charges within the medium; the charges respond to the information, generating directional force effects (charge displacement/magnetic moment reorientation), which then form macroscopic effects through the superposition of microscopic existence fields; Permittivity is a quantitative representation of the internal charges' response to external charge information, producing polarization effects, while permeability is a quantitative representation of atoms containing unpaired electron orbitals responding to external magnetic information, producing magnetization effects. Through the deduction using parallel plate capacitor and magnetic medium models, this theory provides a mechanism-clear microscopic explanation for dielectric electromagnetic phenomena, offering a new theoretical framework for related research.
