The SH-generating quantum well layer (pink) and the beam-shaping split-ring metamaterial resonators (the “C”-shaped structures). The phase-coherent emission from individual resonators opens the door for many beam-shaping applications, some of which are presented in the insets. Each device type can be achieved via proper design of individual metamaterial resonators and their arrangement on the surface. Plasmonic phased-array sources* have been the subject of much interest recently. They can perform a many useful optical-beam [...]

A Sandia-led research team† has, for the first time, observed the coherent propagation of thermal phonons‡ in silicon at room temperature—in two-dimensional phononic crystals formed by introducing air holes in a silicon matrix with minimum feature sizes ~250 nm. To separate incoherent from coherent boundary scattering, the team fabricated phononic crystals with a fixed minimum feature size—differing only in unit cell geometry (see Figure 1). This research was presented in a paper in Nature Communications. Figure [...]

Wind-turbine blades pose a unique set of inspection challenges: from very thick and attentive spar-cap structures to porous bond lines, varying core material, and a multitude of manufacturing defects of interest. The need for viable, accurate, nondestructive inspection (NDI) technology becomes more important as the cost per blade—and lost revenue from downtime—grows. Under its Blade Reliability Collaborative program, Sandia is quantitatively assessing the performance of a wide range of NDI methods that are currently deployed, [...]

Structural Health Monitoring and Prognostics Management for Offshore Wind Plants

Offshore wind energy could potentially play a significant role in helping the nation establish a diversified energy-generation portfolio composed of clean, renewable resources. A current obstacle to offshore wind energy is that most projections put offshore wind farm operations and maintenance (O&M) costs between 2 to 5 times the current average O&M costs for onshore wind farms. One way in which those costs may be reduced is through a simple, yet effective structural health monitoring [...]
