利用偏振光测量了具有相同晶格常数但尺寸不同的十字形孔的透射率，研究了孔周围局域电荷振荡的变化。通过具有不同孔形状的相似排列的周期孔阵列，即，还测量了十字形、正方形和矩形。十字形孔产生比用正方形或矩形孔穿孔的孔更大的光透射。(c)2007年，美国物理学会。
In this work, the transmission through cross shaped hole with different sizes but the same lattice constant was measured with the polarized light to investigate the variation of localized charge oscillation around the hole. The comparison between the transmission intensities through the similarly arranged periodic hole array with different hole shapes, i.e., cross, square, and rectangular, were also measured. The cross shaped hole gives rise to a larger transmission of light than those perforated with square or rectangular hole. (c) 2007 American Institute of Physics.
