Tuning the focusing spot of plasmonic nanolens by aspect ratio under linear polarization
《Chinese Optics Letters》2014年第1期62-65,共4页曹水艳 鱼卫星 王成 付永启 
supported by the National Natural Science Foundation of China(Nos.90923036,60977041,60877021,and 61077010);the 100 Talents Program of Chinese Academy of Sciences,and the Ministry of Science and Technology of China(No.2010DFR10660)
A new plasmonic nanolens that can be tuned by varying the circular structure into an elliptical annulus and the aspect ratio from l to 0.1 and 1 to 2, respectively, is proposed. Using the rigorous finite-difference an...

Tunability of graded negative index-based photonic crystal lenses for fine focusing
《Chinese Physics B》2013年第9期391-394,共4页晋蕾 朱清溢 付永启 
supported by the National Natural Science Foundation of China (Grant Nos. 11079014 and 61077010)
Graded negative refractive index-based photonic crystal (PC) lenses are designed by gradually modifying the sizes of air holes along the transverse direction for focusing the incident plane wave. To study the tunabi...
