Achieving reconfigurable electromagnetically induced transparency (EIT) metamaterials (MM) lays the ground for simplifying the MM design for different application scenarios. Mechanical reconfiguration with deformable MM is expected to provide a scheme to dynamically configure the MM’s properties without employing additional electronic components. In this study, we examine a classical EIT MM and propose a modulation mechanism based on mode coupling for the mechanical reconfiguration of EIT MM. This mechanism is verified through analyses of the electric field and surface charge density distributions. Additionally, a robust-coupled Lorentz oscillator model is used to explain the coupling mechanism, with results that are in good agreement with simulations and experiments. We further design and fabricate an EIT MM with stretchable sections to demonstrate the feasibility of the proposed reconfiguration scheme, which is capable of dynamically regulating the bandwidth and group delay of the EIT MM by applying tensile strain.
