摘要：

Modal loss coefficients for a planar leaky wave-guide are obtained by two new methods. One is a numerical calculation combining optical thin film theory with optical wave-guide theory; another is an analytical derivation based on analogy to Beer's law. Considering the influence of the modal loss, a modified mode equation for the planar leaky wave-guide is obtained, which greatly increases the accuracy of the refractive index and thickness of the thin film in a planar leaky wave-guide coupler (prism I film I substrate).
