Achieving qualified absorption from low to high frequency is challenging due to impedance matching requirements in the structure. Herein, the proposed structure achieves a wide absorption bandwidth (over 90% absorptivity) from 2.4 GHz to 300 GHz. Moreover , the absorption efficiency of electromagnetic waves reaches (99%) from 4 GHz to 300 GHz. For transverse electric (TE) and transverse magnetic (TM) modes, the proposed structure behaves the same up to 45° when exposed to oblique incidences. The total thickness of the designed absorber is 3.6 mm, corresponding to 0.03λ0 at the lowest operating frequency. In addition, the proposed absorber is 1 compared with previous reports of radar bands. It is observed that it offers superior practical feasibility and is a promising candidate for S, C, X, Ku, K, Ka, V, W, and millimeter band radar applications.
