我们研究了电磁波在基本极化情况s和p下通过完全导电圆柱体阵列的传播。我们使用了广义瑞利恒等式方法，并证明了对于p极化，基本带定义了一个不符合静电的有效折射率。我们展示了非常稀阵列的光子带结构，它们趋向于预期的自由传播形式。我们还研究了接近触摸的阵列，其中8和p极化行为之间存在非常有趣的差异。
We study the propagation of electromagnetic waves through arrays of perfectly conducting cylinders for both fundamental polarization cases s and p. We use a generalized Rayleigh identity method and show that for p polarization the fundamental band defines an effective refractive index not in keeping with electrostatics. We exhibit the photonic band structures for very dilute arrays, where they tend towards the expected free-propagation form. We also study them for arrays approaching touching, where very interesting difFerences between 8 and p polarization behavior are manifest.
