Based on the four native axioms of linear elastic transverse wave field (Yuanji Field), this paper derives the topological structure of electrons as 2D orthogonal closed standing waves, and obtains the theoretical value of the fine structure constant 1/α ≈ 137.0360, which is in excellent agreement with the CODATA 2018 recommended value (relative error 2.3×10⁻⁷). All derivations are based on first principles with no adjustable parameters.
