[<a href=\"https:\/\/app.box.com\/s\/vc6xejqa97tvdrk46d6p\">pdf<\/a>]<\/p>\n<p>In this work, we report the design of a wavelength-tunable infrared metamaterial by tailoring magnetic resonance condition with phase transition of vanadium dioxide (VO<sub>2<\/sub>). Numerical simulation based on the finite-difference time-domain method shows a broad absorption peak at the wavelength of 10.9 mm when VO<sub>2<\/sub> is a metal, but it shifts to 15.1 mm when VO<sub>2<\/sub> changes to dielectric phase below its phase transition temperature of 68\u00b0C. The large tunability of 38.5% in the resonance wavelength stems from the different excitation conditions of magnetic resonance mediated by plasmon in metallic VO<sub>2<\/sub> but optical phonons in dielectric VO<sub>2<\/sub>. The physical mechanism is elucidated with the aid of electromagnetic field distribution at the resonance wavelengths. A hybrid magnetic resonance mode due to plasmon-phonon coupling is also discussed. The results here would be beneficial for active control of thermal radiation in novel electronic, optical and thermal devices.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; &nbsp; &nbsp; &nbsp; Congrats to Hao Wang and Yue Yang for the nice work!
