A　microwave　tunable　metamaterial　utilizing　the　semiconductor-to-metal　transition　of　vanadium　dioxide　(VO2)　is　proposed,　experimentally　demonstrated　and　theoretically　scrutinized.　Basic　concept　of　the　design　involves　the　combination　of　temperature-dependent　hysteresis　in　VO2　with　resonance　induced　heating,　resulting　in　a　nonlinear　response　to　power　input.　A　lithographically　prepared　gold　splitrings　resonator　(SRR)　array　deposited　with　VO2　thin　film　is　fabricated.　Transmission　spectra　analysis　shows　a　clear　manifestation　of　nonlinearity,　involving　power-dependence　of　resonant　frequency　as　well　as　transmitted　intensity　at　both　elevated　and　room　temperature.　Simulation　performed　with　CST　Microwave　Studio　conforms　with　the　findings.　The　concept　may　find　applications　in　transmission　modulation　and　frequency　tuning　devices　working　under　microwave　frequency　bands.
