Abstract A low-frequency wideband, polarization-insensitive and wide-angle metamaterial absorber (MA) is designed, simulated and analyzed. This MA consists of a periodic arrangement of cave-disk resonator (CDR), square resistive film (RF), and metal ground plane (GP) (a 0.8-mm-thick FR-4 dielectric spacer is sandwiched in between CDR and RF, and another 1.2-mm-thick FR-4 dielectric spacer is inserted in between RF and GP). The simulated results based on the finite integration technology (FIT) indicate that the absorption of the MA is greater than 90% and almost perfectly impedance-matched to the free space in the whole frequency range of 1 GHz-7 GHz. The simulated absorptions under the conditions of different polarization and incident angles indicate that this composite structure absorber is polarization-insensitive and wide-angle. Furthermore, the distribution of the power loss density indicates that the wideband absorptivity is mainly from the composite electromagnetic loss of the CDR and RF. This design provides an effective and feasible way to construct a low-frequency wideband absorber.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
