Modelling of 1-D Multilayer Periodic Structure Deeply or Fully Etched using the Leaky Mode Propagation Method

A model of deeply and fully etched gratings, also identified as one-dimensional waveguide Photonic BandGap structures (PBG) [1], based on the Leaky Mode Propagation method, has been developed to perform a complete analysis of the electromagnetic (e.m.) wave propagation in the structure, assumed of finite extension, i.e. to determine mode propagation constants, electromagnetic field harmonics and total field distribution, transmission and reflection coefficients, total forward and backward power flow in the structure, guided power and total losses.
