In this manuscript, we present on a thermally tunable electric Mie resonance of dielectric cut-wire type metamaterial. Dielectric cut-wire exhibits Lorentz-type frequency dependent negative effective permittivity followed by zero value around its fundamental Mie resonance, resulting from dipole-oscillation of displacement currents. Furthermore, the operation frequency of electric resonance frequency can be varied by wire length and temperature variation. As environmental temperature changes by 40 °C, electric Mie resonance can be reversibly tuned by 1000 MHz, due to the thermal dependent permittivity character of ceramic.
