Area of Science:

• Electromagnetics
• Materials Science
• Additive Manufacturing

Background:

• Metasurfaces offer unique electromagnetic properties.
• 3D printing enables complex structure fabrication.
• Conductive filaments present opportunities and challenges for electromagnetic applications.

Purpose of the Study:

• To design, construct, and measure 3D-printed Sievenpiper metasurfaces.
• To evaluate the electromagnetic performance of 3D-printed metasurfaces.
• To compare experimental results with simulated ideal cases.

Main Methods:

• Utilized a combination of conductive filament and polylactic acid (PLA) for 3D printing.
• Fabricated various Sievenpiper metasurface structures.
• Performed electromagnetic measurements to characterize stop-band behavior.

Main Results:

• Demonstrated good agreement between measured and simulated electromagnetic stop-band behavior for the 3D-printed metasurfaces.
• Observed higher transmission losses in the 3D-printed structures compared to simulated ideal cases.
• Attributed increased losses to the inherent characteristics of the conductive filament.

Conclusions:

• Fully 3D-printed Sievenpiper metasurfaces are feasible for electromagnetic applications.
• The conductive filament impacts transmission losses, requiring further material optimization.
• Experimental validation confirms the potential of additive manufacturing for creating functional metasurfaces.
