Abstract

In this paper

a reconfigurable terahertz ultra-wideband absorber with umbrella structure based on graphene and vanadium dioxide is proposed

which greatly expands the absorption bandwidth of the terahertz absorber and has the advantages of functional reconfiguration and large modulation depth. The absorber consists of an umbrella shaped VO

patch

a polyethylene cycloolefin copolymer (Topas) dielectric layer

graphene layer

and a metallic reflector. When VO

is in the insulating state and the Fermi level of graphene is 0 eV

the absorber exhibits total reflection characteristics in the whole terahertz band. When VO

is in the metal state and the Fermi level of graphene is 0.75 eV

the absorber achieves ultra-wideband absorption in the frequency range of 3.57~10 THz

with an average absorption rate of more than 94% and an absorption bandwidth of up to 6.43 THz. By adjusting the conductivity of VO

and the Fermi level of graphene at the same time

the maximum modulation depth of 97.9% (at 4.3 THz) and 96.8% (at 8.25 THz) can be achieved at the two perfect absorption points

which has good switching characteristics. In addition

the absorber has polarization insensitivity and wide-angle absorption characteristics. In the range of 0~35°

the absorptivity of the absorber is more than 90% in the range of 3.57~10 THz bandwidth. The ultra-wideband reconfigurable terahertz absorber will have potential applications in tunable broadband absorber

stealth devices

thermal detection

terahertz switches and other fields.
