Abstract In this paper, we present a proof-of-concept of a new approach to achieving tailored resonant frequency temperature coefficients in dielectric meta-atoms.The technique involves introducing a thermally expanding or contracting material joining the active high permittivity dielectric absorbers.Both simulation and experiment show Frameless Glass Shower Door Parts that by careful design of the element size and appropriate choice of thermomechanical intermediate layer material, increased or decreased resonant frequency shift temperature sensitivity is possible.Once the active dielectric material is chosen, and a Upright Freezer meta-atom design determined, we show the resonant frequency shift depends on the thermal expansion coefficient of the intermediate layer.This work demonstrates the feasibility of manipulating the blue or red shift of metamaterial devices by introducing temperature responsive intermediate layers into meta-atoms.
