We present a very accurate and fast model of Photonic Band-Gap (PBG) structure characterized by a two-dimensional (2D) periodic change of the refractive index and finite height, therefore named quasi 3D PBG. The model is based on the Floquet-Bloch formalism, we have demonstrated to be particularly suitable to design PBG devices. The model allows both a significantly faster convergence than other more complex numerical models, and a greater accuracy than other approximate models. Simulations run very quickly providing the geometrical dimensions, the forbidden frequency range, the propagation constants, the total field distribution and the modal losses.
