In this paper, a single-layer broadband low-profile ultrathin metamaterial microwave absorber is proposed for wide angle of incidence. The proposed absorber provides triple-band absorption under normal incidence of electromagnetic wave with two peaks lying in X-band and one in Ku-band. The unit ...

The beam shaping principle provides a straightforward route to control arbitrary high-order modes; however, its great potential has been significantly constrained by the complicated designs based on the traditional Mach–Zehnder interferometer architecture. Here we propose, for the first time, a practicab...
A hybrid acoustic metamaterial is proposed as a new class of sound absorber, which exhibits superior broadband low-frequency sound absorption as well as excellent mechanical stiffness/strength. Based on the honeycomb-corrugation hybrid core (H-C hybrid core), we introduce perforations on both top fa...
Broadband absorption The normal incidence absorptivity simulated based on different EM parameters is shown in Fig. 6(a). The low permittivity causes impedance mismatch, so the structure has weak absorption in the frequency band. When the filling rate is higher than 20 wt%, the absorption peaks ...

To achieve broadband high absorption, admittance matching and high extinction of the equivalent layer must be sustained over a wide range of wavelengths. This work develops a design method that is based on the normalized admittance diagram in which the loci of the layered system are traced. The ...

From an experimental perspective, nonlinear metamaterials need to be designed, fabricated, and tested from the resonator level to the metamaterial level to confirm the proposednonlinear effectin practical manners, which requires repeatable and slow samp...
