Wideband frequency tunable metamaterial absorber by splicing multiple tuning ranges
A band-splicing strategy is proposed to greatly extend the tunable bandwidth of metamaterial absorbers (MMAs) based on circular split-rings (CSRs) containing varactors. In this strategy, the CSRs are split into multiple segments with the absorption frequency continuously tunable in a pre-set frequen...
