Extraordinary optical transmission (EOT) through dielectric screens periodically loaded with sub-wavelength 1D discontinuities, such as apertures or metallic insets is analyzed. The results of the analysis and computational electromagnetic simulations show that the transmission is higher for for metallic inclusions than for empty slits. This effect confirms that EOT is a quite general property of weakly transparent periodic diffraction screens and opens the door to optically induced EOT in photo-conductive semiconductor screens.
分析了通过周期性加载亚波长一维间断（如孔径或金属嵌入物）的介电屏蔽的超常光学传输（EOT）。分析结果和计算电磁模拟表明，金属内含物的传输比空狭缝的传输更高。这一效应证实了EOT是弱透明周期性衍射屏的一个相当普遍的特性，并为光电导半导体屏中的光诱导EOT打开了大门。
