Summary
This study introduces a deep-learning algorithm for designing reconfigurable metamaterial absorbers (MAs) using origami and kirigami structures. The novel approach enables fast inverse design, leading to polarization-insensitive ultrabroadband absorption with tunable properties.
Area of Science:
- Metamaterials
- Electromagnetics
- Mechanical Engineering
- Artificial Intelligence
Background:
- Reconfigurable metamaterial absorbers (MAs) offer tunable bandwidth and amplitude but face design and fabrication challenges.
- Origami and kirigami structures present a promising avenue for MAs due to their combined mechanical and electromagnetic properties.
- Existing design methods are often iterative and complex, hindering the development of high-performance MAs.
Purpose of the Study:
- To develop a fast inverse design algorithm for reconfigurable origami metamaterial absorbers (MAs) using deep learning.
- To create a novel accordion-origami coding MA with switchable absorption and reflection properties.
- To enhance polarization-insensitive absorption by integrating a kirigami polarization rotation surface.
Main Methods:
- A deep-learning-based algorithm was employed for the inverse design of origami MAs.
- An accordion-origami coding MA was designed and fabricated, demonstrating tunable electromagnetic responses.
- A kirigami polarization rotation surface was integrated to achieve polarization-insensitive absorption.
Main Results:
- The developed algorithm enabled fast inverse design of origami MAs.
- An accordion-origami MA exhibited tunable absorption (5.5-20 GHz) and high reflection (2-20 GHz) under y-polarized waves.
- The stacked origami-kirigami MA achieved polarization-insensitive ultrabroadband absorption (4.4-20 GHz) and tunable mechanical properties.
- Low-concentration MXene-PEDOT:PSS inks were developed for screen printing metamaterials.
Conclusions:
- The deep-learning approach offers a paradigm for efficient design of reconfigurable MAs.
- The integrated origami-kirigami structure provides polarization-insensitive, tunable electromagnetic absorption.
- The developed fabrication method using MXene-PEDOT:PSS inks allows for low-cost, high-performance metamaterial production.
