Silver nanoparticles grown in nanochannels of anodic aluminum oxide on a grating form a surface-enhanced Raman scattering (SERS) substrate with the double resonance from both localized and delocalized ...

Abstract: We demonstrate a grating coupler with reduced back reflection on silicon-on-insulator (SOI) platform. Each grating tooth of the grating coupler is uniformly divided into multiple sub-teeth ...

A new book by Alex Thompson and Jake Tapper reveals how Democratic insiders betrayed Americans by lying about President Biden ...

Abstract: The reflection characteristics of super-structure-grating (SSG) reflectors are demonstrated theoretically and experimentally. The periodic multireflection peaks with high reflectivities of ...
