Measuring high aspect ratio and composite micro-trenches without damage is critical for advanced microfabrication, yet conventional coherence scanning interferometry often suffers from a low signal-to ...

Abstract: Current source inverters (CSIs) are attractive options for battery energy storage systems (BESS) due to their inherent capabilities for voltage boosting and short-circuit protection. This ...

Abstract: This paper proposes and demonstrates an arbitrarily tunable multi-frequency pulse modulation scheme based on an active fiber loop, which effectively suppresses the interference fading effect ...
