•Bilayer metamaterials with an excellent capability to tailor and tune EM responses.•Controlled by different SRR units combination and/or surrounding dielectrics.•Easy and quick design for complex multi-response metamaterials.•An excellent candidate for novel terahertz applications.
The electromagnetic (EM) responses of a series of single layer and bilayer terahertz (THz) metamaterials (MMs) were systematically investigated. Bilayer split ring resonators (SRRs) consisting of different SRR units and/or surrounding dielectrics show an excellent capability to tailor and tune EM responses using the combined responses in the SRRs in different layers. By avoiding complex interactions between the layers, easy and quick design for complex multi-responses MMs can be carried out. This tailoring and tuning capability of bilayer MMs shows a great potential for many novel THz applications such as signature control, chem/bio detection, and multi-response sensors.
