摘要	A new plasmonic nanolens that can be tuned by varying the circular structure into an elliptical annulus and the aspect ratio from 1 to 0.1 and 1 to 2, respectively, is proposed. Using the rigorous finite-difference and time-domain algorithm, we find that when the aspect ratio ranges from 1 to 0.1, a good linear relationship exists between the aspect ratio and focusing spot size at the full-width at half-maximum in the x- and y-directions, respectively. The corresponding calculated FWHM ranges from 96 x 126 (nm) to 15 x 52 (nm) (Full Width at Half Maximum).
