The net of a 3D shape is what a shape looks like when opened into a 2D shape. The net can help to show the areas of each face that make up the surface area of a shape. The same units are needed for ...

Abstract: We show in simulation and experiment that the coherent coupling of electric fields between elements of a triangular photonic crystal vertical cavity surface emitting laser array can be ...

Abstract: We discuss algorithms and numerical challenges in constructing and resolving spectral problems for photonic crystal surface-emitting lasers (PCSELs) with photonic crystal layers and large ...

The IAEA launched the Forum on the Safety of Near Surface Disposal in 2017 to improve the safety of near surface disposal facilities by developing guidance, methods and tools, exchanging information ...

There is no perfect place to live. Anyone house-hunting can attest that finding a town or city that ticks every box is all but impossible. The schools are excellent but the railway connections are ...
