研究目的
To propose a millimeter-scale waveguide grating antenna (WGA) with high directionality for applications in Lidar and data communication systems.
研究成果
A millimeter-scale waveguide grating antenna with high directionality is proposed, achieving over 86% directionality with a 100 nm bandwidth and a peak close to 90%. The structure's length and directionality make it suitable for remote detection applications.
研究不足
The simulation of a millimeter-scale WGA is beyond the computing capability of the computer, requiring estimation methods for total length.
1：Experimental Design and Method Selection:
The study involves the simulation of a WGA consisting of a silicon waveguide and a silicon nitride layer to achieve high directionality.
2：Sample Selection and Data Sources:
