Calculation of Guided Modes and Leaky Modes in Photonic Crystal Slabs

         

摘要

@@ The scattering matrix S describing photonic crystal slabs is formulated. A new method is introduced to solve the eigenfrequency ω for a given Bloch wave vector K from the equation det S-1 (ω, K) = 0. Using this method,we can obtain not only guided modes but also leaky modes in photonic crystal slabs with a higher-frequency resolution than that of the FDTD method.
