With the development of radar and communication system, frequency selective rasorber (FSR) is in great need. In this article, a flexible rasorber based on graphene is presented and investigated. A passband with small insertion loss and two absorption bands with high absorptivity below and above the passband is realized. Without welding lumped elements, our design can be applied to wide wavelength regions from microwave to low terahertz range, and also conformal situations. Besides, by integrating graphene sandwich structure (GSS), tunable transmission at the passband of the rasorber is realized, which makes our rasorber have the function of energy manipulation. For experimental demonstration, the rasorber prototype is fabricated and measured at microwave region; the fabricated sample shows good flexibility and good tunability, demonstrating that our radome has great application prospect in the field of electromagnetic stealth, compatibility, and protection.
