We use our previous formulation for cylinder gratings in conical incidence to discuss the photonic band gap properties of woodpile structures. We study scattering matrices and Bloch modes of the woodpile, and use these to investigate the dependence of the optical properties on the number of layers. We give data on reflectance, transmittance and absorptance of metallic woodpiles as a function of wavelength and number of layers, using both the measured optical constants of tungsten and using a perfect conductivity idealization to characterize the metal. For semi-infinite metallic woodpiles, we show that polarization of the incident field is important, highlighting the role played by surface effects as opposed to lattice effects.
我们使用之前关于圆锥入射下圆柱光栅的公式来讨论木堆结构的光子带隙特性。我们研究了木堆的散射矩阵和布洛赫模式，并利用这些来研究光学性质对层数的依赖性。我们给出了金属木堆的反射率、透射率和吸收率数据，这些数据是波长和层数的函数，分别使用了钨的实测光学常数以及用理想的完美电导率来表征金属的情况。对于半无限大的金属木堆，我们表明入射场的偏振很重要，突出了表面效应相对于晶格效应所起的作用。
