Conventional high-temperature plasma deuterium-tritium fusion relies on ultra-high temperatures of hundreds of millions of degrees and strong magnetic confinement to drive nuclear reactions, which inherently suffers from high operating energy consumption, poor reaction controllability, long-term radioactive activation of chamber materials, and difficulty in achieving stable net energy gain. Based on a unified underlying physical model of electromagnetic fields and space particle coupling, this paper constructs a complete low-energy dual resonant lattice fusion system matched with an optimized external particle feeding engineering scheme. The system adopts an isolated confined structure for single protons under vacuum, and uses zero-angular-momentum coaxial electron incidence to produce neutrons at room temperature. A 0.782 MeV intrinsic energy barrier exists for the conversion of protons and electrons into neutrons in free space; to address this issue, localized coaxial vortex photonic resonant fields are adopted to realize effective mass correction of electrons under specific boundary conditions, whose physical picture is analogous to quasiparticle effects in intense laser fields, without macroscopic high-energy acceleration of electrons. The generated cold neutrons are uncharged and free of Coulomb barriers when contacting protons, enabling spontaneous close-range coupling to form deuterium nuclei with a single reaction releasing 2.22 MeV of intrinsic nuclear binding energy. Compared with conventional deuterium-tritium fusion that releases 17.6 MeV per reaction, the proposed system operates without extreme high-temperature conditions and generates no high-energy activating neutrons. A multi-layer gradient dense spherical dielectric structure is designed to progressively downconvert high-energy photons emitted from nuclear reactions into usable thermal energy via coherent scattering, realizing fully enclosed radiation recovery. The entire particle supply adopts an external independent preparation architecture, where protons and neutrons are directionally fed into the main reaction chamber through vacuum pipelines, greatly simplifying the internal core structure and supporting long-term steady-state continuous operation of the device. Bare deuterium nuclei generated from coupling can be extracted from the chamber, neutralized to form deuterium gas, and deliver dual benefits of power/heat generation and added-value industrial raw materials. The system only uses ordinary water as the basic raw material, featuring safe operation, flexible regulation and low engineering implementation thresholds. Refined engineering practices including precision vacuum chamber machining, coaxial electron beam calibration and particle timing synchronization are reserved for iterative optimization in subsequent applied research.
