AI Technical Summary
Existing electromagnetic wave absorbers face challenges in achieving broad angular robustness and reasonable thickness while maintaining high absorption efficiency, particularly in oblique incidence, and require improved manufacturing methods for complex shapes.
A two-dimensional network of spherical cap-shaped resonators made of dielectric or magneto-dielectric materials, combined with additive manufacturing, particularly using a magnetically charged thermoplastic matrix like COC5-H10, to enhance angular performance and absorption efficiency.
The spherical cap-shaped resonators provide improved angular robustness and absorption efficiency across a wide frequency band, including oblique incidences, with reduced thickness and flexibility, outperforming cylindrical resonators in terms of absorption levels and angular stability.
