It may look like an alien spaceship, but this is a photo of a type of snow crystal known as a capped column. Under certain temperature and humidity conditions in the clouds above us, nature can ...

In this article, we have theoretically investigated the performance of graphene-hexagonal Boron Nitride (hBN) multilayer structure (hyper crystal) to demonstrate all angle negative refraction along ...

We have designed a unique structure for a liquid sensor based on two-dimensional PCs with a triangular lattice constant in the periodicity by drilling a hexagonal cylinder in a dielectric host ...
