In this paper, using an enhanced homogenization method, the behavior of a one-dimensional guided-mode resonant structure with zero-contrast configuration is investigated. The proposed method demonstrates significantly enhanced accuracy compared to conventional Effective Medium Theory (EMT)-based approaches. The modal behavior of the sample structure is analyzed using this method, revealing excellent agreement with rigorous numerical calculations performed via the Rigorous Coupled Wave Analysis (RCWA) method. The proposed enhanced homogenization method serves as an excellent candidate for rapid preliminary design of periodic optical devices and provides an efficient starting point for optimization algorithms. The technique bridges the gap between simplified EMT and time-consuming full-wave simulations, offering a practical tool for resonant photonic structure design.
