Although substantial progress has been made in the control of electromagnetic transparent cloaking, developing an effective method to achieve broadband transparent cloaking remains an urgent and core engineering physics challenge. Herein, theoretical derivation clarifies that the core phase compensation conditions required for a broadband transparent cloaking device exhibit dispersive characteristics. Furthermore, a novel method for achieving broadband transparent cloaking via dispersion engineering is proposed. Through the refined regulation of the phase dispersion properties of Huygens’ metasurfaces, a meta-cloak in constructed, which effectively realizes broadband (10.0-11.5 GHz, 13.95%) transparent cloaking for a dielectric cylinder, verifying the feasibility of the proposed method. Full-wave simulations are in good agreement with experimental results, confirming consistent near-field wavefront preservation and far-field scattering suppression, with phase front correlations cross-validated by experiments and theory. This work establishes a paradigm for broadband electromagnetic transparent cloaking, bridging critical gaps between broadband performance, scattering suppression, and scalable manufacturing for next-generation radar evasion and communication technologies.
