Abstract

We demonstrate thermal tuning of the inductive capacitive (LC) resonance in terahertz metamaterials made up of gold split-ring resonator (SRR) arrays on ferroelectric bulk Strontium Titanate (STO) substrates. Heating the metamaterial from temperature of 150 K to 425 K causes as high as 69% blue shift in metamaterial resonance frequency due to the change in refractive index of the substrate.
