研究目的
To design phase coded surfaces using a remodeled Jerusalem cross meta-element for wave manipulation and RCS reduction.
研究成果
The proposed phase quantized supercells demonstrate effective wave manipulation and RCS reduction, with model-2 showing superior performance in diffusing reflected beams and reducing RCS by more than 10 dBsm from 9 GHz to 11 GHz.
研究不足
The study is limited to X-band frequencies and the performance is validated through simulations and limited experimental measurements.
1:Experimental Design and Method Selection:
The study involves the design of a remodeled Jerusalem cross meta-element for phase variation and quantization. Two 3-bit phase quantized supercells are proposed and simulated for scattering properties comparison with traditional chessboard type supercells.
2:Sample Selection and Data Sources:
The meta-element is printed on a low-cost FR4 substrate with a metallic ground. Simulations are performed using CST Microwave Studio.
3:List of Experimental Equipment and Materials:
FR4 substrate, copper coating, CST Microwave Studio software.
4:Experimental Procedures and Operational Workflow:
The meta-element's geometrical parameters are varied to achieve 360° phase variation. Two supercell models are designed, simulated, and compared for RCS reduction.
5:Data Analysis Methods:
Full-wave simulations are conducted to analyze the scattering properties and RCS reduction.
