Journal ArticleDOI
Sub-Diffraction-Limited Optical Imaging with a Silver Superlens
TL;DR: This work demonstrated sub–diffraction-limited imaging with 60-nanometer half-pitch resolution, or one-sixth of the illumination wavelength, using silver as a natural optical superlens and showed that arbitrary nanostructures can be imaged with good fidelity.
Journal ArticleDOI
Far-field optical hyperlens magnifying sub-diffraction-limited objects.
TL;DR: Experimental demonstration of the optical hyperlens for sub-diffraction-limited imaging in the far field and opens up possibilities in applications such as real-time biomolecular imaging and nanolithography.
Journal ArticleDOI
Ultrasonic metamaterials with negative modulus
Nicholas X. Fang,Dongjuan Xi,Jianyi Xu,Muralidhar Ambati,Werayut Srituravanich,Cheng Sun,Xiang Zhang +6 more
TL;DR: A new class of ultrasonic metamaterials consisting of an array of subwavelength Helmholtz resonators with designed acoustic inductance and capacitance with an effective dynamic modulus with negative values near the resonance frequency is reported.
Journal ArticleDOI
Optical Negative Refraction in Bulk Metamaterials of Nanowires
Jie Yao,Zhaowei Liu,Yongmin Liu,Yuan Wang,Cheng Sun,Guy Bartal,Angelica M. Stacy,Xiang Zhang,Xiang Zhang +8 more
TL;DR: Bulk metamaterials made of nanowires that show negative refraction for all incident angles in the visible region are reported, resulting in a low-loss and a broad-band propagation at visible frequencies.
Journal ArticleDOI
Projection micro-stereolithography using digital micro-mirror dynamic mask
TL;DR: In this article, a high-resolution projection micro-stereolithography (PμSL) process by using the Digital Micromirror Device (DMD™, Texas Instruments) as a dynamic mask is presented.
