Abstract: In recent years, reconfigurable intelligent surfaces (RISs) have attracted significant attention from both academia and industry due to their ability to manipulate electromagnetic waves in ...

The introduction of dynamic arrays triggered the biggest change to how we work with Microsoft Excel formulas in years, if not decades. They allow a single formula to spill multiple results into ...

Abstract: We present our recent progress in integrated silicon optical phased array (OPA), which overcomes long-standing challenges in achieving high-performance solid-state 2D optical beam steering.

ABSTRACT: The terrain factors have a direct impact on the structure and spatial synthesis of the glide path antenna. Analyzing various terrain factors can effectively control the adjustment effect of ...
