Why is it important?
The simulation result of the infinite graphene sheet shows that the dispersion HIE-FDTD method has high computational accuracy and the computational time is greatly reduced compared with the dispersion FDTD method. By using the dispersion HIE-FDTD method, it validates that the graphene sheet can be used as a broadband absorber.
Perspectives
This paper proposes a dispersion hybrid implicit explicit-finite difference time domain(HIE-FDTD) method for simulating the graphene-based absorber at THz. The dispersion HIE-FDTD method has high computational accuracy and is extremely more efficient than the dispersion FDTD method. It is more useful for simulating the graphene-based devices.
