Lossless Matching Layer for Silicon Lens Arrays At 500 GHz Using Laser Ablated Structures

We present the design, fabrication and characterization of a broadband lossless matching layer for silicon lens arrays. The proposed matching layer is based on silicon frusta (truncated pyramids) on top of the lens array fabricated by means of laser ablation. This matching layer is advantageous over quarter-wavelength dielectric matching...

Anticipatory Life Cycle Assessment of sol-gel derived anti-reflective coating for greenhouse glass

Environmental analysis should be performed early in the Research and Development (R&D) phases of new technologies to timely determine potential impact and, thereby, include prevention and minimization of unfavorable ecological impact into the innovation process. Here, we demonstrate the application of anticipatory Life Cycle Assessment ...
