Evaluation of Geogrid-Aperture Size on the Behavior of Reinforced Fine-Sand Supporting a Square Footing [PDF]
Port Said Engineering Research JournalFine-sand soils cannot support the design loads due to their low load-bearing capacity. Soil reinforcement with geogrid-layers is a common technique to increase the low bearing capacity of fine-sand.

Active Two-dimensional Steering of Radiation from a Nano-Aperture
, 2018 We experimentally demonstrate control over the direction of radiation of a beam that passes through a square nano-aperture in a metal film. The ratio of the aperture size and the wavelength is such that only three guided modes, each with different ...
