研究目的
Investigating the design of a waveform-selective cloak for antenna applications that can switch its behavior based on the impinging signal's waveform.
研究成果
The study demonstrates the feasibility of a waveform-selective mantle cloak for antenna applications, capable of switching its behavior based on the illuminating signal's waveform. This paves the way for advanced and unconventional functionalities in cloaking devices.
研究不足
The PW should have at least a pulse duration of 10 ns due to the bandwidth performance of the mantle cloaking technique.
1：Experimental Design and Method Selection:
The study involves designing a conventional mantle cloak loaded with a lumped-element circuit to achieve waveform-selective behavior.
2：Sample Selection and Data Sources:
A wire antenna is used as the object to be cloaked.
3：List of Experimental Equipment and Materials:
The setup includes a metallic-strip metasurface (MTS) and a lumped-element circuit consisting of a 4 diodes full-bridge rectifier, an inductance (L), and a resistor (R).
4：Experimental Procedures and Operational Workflow:
The MTS is illuminated by either a pulse wave (PW) or a continuous wave (CW), and the response is analyzed.
5：Data Analysis Methods:
Numerical simulations are carried out using CST Studio Suite to analyze the current flow and cloaking effectiveness.
