Abstract: The interaction of an electromagnetic wave with a nonstationary medium is studied. The reflectances and transmittance of light through a material that experiences a one-time refraction index switch are calculated. It is shown that by adjusting the parameters of the switching time profile, it is possible to control the amplitudes of the reflected and transmitted waves. It has been specified that for efficient conversion of light using this class of media, the switching duration must be an order of magnitude shorter than the wave period.

Keywords: photonics, metamaterials, nonstationary media, spatiotemporal heterogeneity.
