Researchers from the University of Science and Technology of China (USTC) have unveiled a planar optical device that significantly enhances the capabilities of dark-field microscopy, achieving ...
(a) Working principle of metasurface displacement measurement can be understood as the detection of the power of different modes of the converted light. The incident irradiated on the metasurface and ...
Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...
Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...
At 633 nm wavelength, the DSPP tip generated roughly six times the electric field strength of a comparable asymmetric double-slit probe. Stable nanofocusing held across a 580 to 800 nm range, with the ...
A research group led by Assistant Professor Takafumi Tomita and Professor Kenji Ohmori at the Institute for Molecular Science, National Institutes of Natural Sciences, has developed a new microscopy ...
