Abstract :
A dual-band metamaterial absorber based on asymmetrical snowflake-shaped resonators is presented. The two absorption bands can be flexibly controlled by adjusting the branch lengths of the snowflake-shaped resonators. Full wave simulation and rigorous experiment are employed to demonstrate the proposed dual-band absorption characteristics.
