光子禁带型遮阳品的设计

Design of sunshade on photonic band gap

为了屏蔽紫外线,提出光子禁带型遮阳品,分别用传输矩阵、时域有限差分法计算紫外线在1维、2维光子禁带型遮阳品中的透射率。结果表明,选取合适的参量,可以设计紫外线的1维、2维光子禁带遮阳品;入射角对1维、2维遮阳品的禁带波长下限都有较大影响。

In order to shied the ultraviolet, sunshade on photonic band gap was proposed, the transmissivity of the ultraviolet radiation in 1-D and 2-D sunshade on photonic band gap was calculated by means of transfer matrix and the finite difference time domain method. The result shows that 1-D and 2-D sunshade on photonic band gap can be designed if appropriate parameter were selected. Incident angles have a greater impact on low limit of forbidden band.
