This work presents an interactive graphics computational tool for the verification of prestressed concrete beams with post-tensioned bonded tendons to the serviceability limit state (SLS) stress check ...
Scientists have engineered a material so light it can rest on a flower without bending its petals. Known as an aerogel-based structure, it is composed mostly of air while maintaining surprising ...
Abstract: In this letter, a 3-D Eaton lens with gradient refractive index (GRIN) distribution for beam deflection at X-band is designed, fabricated, and measured. The ideal 90° beam bending of Eaton ...
Abstract: This communication describes a beam-tilting technique for planar dipole antennas utilizing gradient refractive-index metamaterial (GRIM) unit-cells. Beam-deflection mechanism is based on the ...
