ABSTRACT Microwave absorbers play a critical role in controlling electromagnetic wave propagation, especially in stealth technology and EMI shielding applications. In this work, we introduce a novel microwave absorber design inspired by the Sakarya chaotic system, which offers broadband and enhanced absorption properties. The proposed absorber structure exhibits distinct fractal geometries that enhance polarisation and angular stability using chaotic attractor‐based patterns. The design process entails generating chaotic datasets from the Sakarya attractor, transforming them into fractal patterns via the Julia set, and fabricating the final structure using resistive ink by a screen printing method on an FR‐4 substrate. Numerical simulations and experimental measurements verify the high absorption efficiency of the structure over a wide frequency range, demonstrating the potential of chaotic attractor‐based designs to enhance electromagnetic absorption performance and offer innovative applications in stealth technology.
