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 ...

Nanoscopy is a field of microscopy that focuses on imaging and studying structures and processes at the nanoscale, typically below the diffraction limit of light. It encompasses various techniques ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to ...

(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 ...

Attempts to break the diffraction limit with 'super lenses' have all hit the hurdle of extreme visual losses. Now physicists have shown a new pathway to achieve superlensing with minimal losses, ...
