  • Radiative energy transfer via surface plasmon polaritons around metal–insulator grating: For better understanding of magnetic polariton Reviewed

    A conventional metal–insulator nanograting has the potential to transmit near-infrared thermal radiation because an electromagnetic wave is resonated in the grating structure. Surface plasmon polaritons (SPPs) take place at the interface between the metal and the insulator with boundaries at both ends. Physicists formulated the resonance frequency of the grating from the Fabry–Pérot interference between the grating thickness and the wavelength of SPPs in a short-range coupled mode. On the other hand, engineering researchers often use a lumped-element model assuming a resonant circuit consisting of an inductance of metal and a capacitance of metal-insulator-metal grating structure. Furthermore, they have considered that the resonant circuit excites a strong magnetic field independent of SPPs. This study compares each physical model and numerical simulation results, then clearly shows that all resonance frequencies and features of the circuit resonance can be described by the Fabry–Pérot interference of the SPPs in short-range coupled mode. Moreover, the estimated resonance frequencies obviously correspond to the local maxima of the transmittance of the nanograting with the various thicknesses and pitches. In this case, a strong magnetic field can be observed in the insulator layer as if it might be an isolated magnetic quantum. However, since materials show no magnetism at near-infrared frequencies, the magnetic response appears due to the contribution of SPPs.

    The metal-insulator transition, exhibited by vanadium dioxide (VO2), significantly affects the refractive index of VO2 depending on its temperature. In this study, multilayered thin films consisting of VO2 were proposed to create a thermal switch switching its emissivity over a broadband wavelength. Through numerical simulations, the multilayered film exhibited a suitable switching property both for the sunlight absorption and radiative cooling depending on its temperature. Moreover, the multilayered thin film showed its potential to automatically control the radiative energy balance to keep its temperature constant without external power.
