Metamolecules deposited on thin dielectric film using standard optical lithography have been investigated numerically and experimentally in the terahertz regime. The topology of the proposed metamolecules is able to achieve a multiple-band frequency response over a broad frequency range. The analysis of the spectral response of the investigated metamaterial reveals that such a feature arises from coupling effects between its individual constituents. The successful demonstration of a THz flexible metamaterial may open up new perspectives towards achieving complex electromagnetic functions involving non-planar metamaterials with simple design and fabrication.
