There are many glorious science-based terms when it comes to surfing. We all talk about swells, of course, the underwater energy that creates a breaking wave. But we'll look at swell angles and ...

The objective of the paper is to understand the wave refraction pattern and littoral sediment transport along the SE coast of India. There are areas of erosion and accretion observed along the coastal ...

Figure 1: Schematics of the degenerate 4WM process on a thin nonlinear film. In this Letter, we experimentally demonstrate nonlinear optical negative refraction in thin metallic nanostructures. We use ...
