利用折射率的实际测量值，用非线性数值方法计算了频率相关金属介质系统的复光子带隙结构。同时计算了透射率和反射率，并与PBG结构进行了比较。对于在近紫外到近红外频率范围内由Ag和MgF2交替层组成的PBG系统，我们发现PBG结构、透过率和反射率的特征与使用Drude模型计算的特征明显不同。这些特征包括德鲁德模型中没有包括的等离子体共振结构。
The complex photonic band gap (PBG) structure of frequency-dependent metallic–dielectric systems, using actual measured values for index of refraction, has been computed using nonlinear numerical techniques. Transmissivity and reflectivity were also computed and compared with the PBG structure. For application to PBG systems consisting of alternate layers of Ag and MgF2 over a range of frequencies from the near ultraviolet to the near infrared, we find that features of the PBG structure, transmissivity, and reflectivity are distinctly different from those computed using the Drude model. These features include plasma resonant structure not included in the Drude model.
