Changing light's polarization can reverse the structure of a patterned light field, opening a new way to control geometry and information in optics. (Nanowerk Spotlight) Light can be bent, focused, or ...

Transformations change the size or position of shapes. In the exam you may be asked to draw and/or describe transformations. In Module 8 (M8), there may be questions on any of the transformations work ...

Developed by Australian PhD student Shekhar Chandra at Monash University, Discrete Geometry Viewer (DGV) is an intriguing piece of software. As a general package, DGV, along with its various ...

Chiral metasurfaces can strongly twist the polarization of light, but how this process unfolds in space and time has been unclear. Scientists in China have now used ultrafast electron microscopy and ...
