Enhanced parametric processes in binary metamaterials
Maxim V. Gorkunov, Ilya V. Shadrivov, Yuri S. Kivshar
We suggest double-resonant (binary) metamaterials composed of two types of magnetic resonant elements, and demonstrate that in the nonlinear regime such metamaterials provide uniqu…
Effect of microscopic disorder on magnetic properties of metamaterials
Maxim Gorkunov, Sergey A. Gredeskul, Ilya V. Shadrivov +1
We analyze the effect of microscopic disorder on the macroscopic properties of composite metamaterials and study how weak statistically independent fluctuations of the parameters o…
Generation of high-frequency radiation in semiconductor superlattices with suppressed space-charge instabilities
Kirill N. Alekseev, Natalia V. Demarina, Maxim V. Gorkunov
We theoretically investigated the scheme allowing to avoid destructive space-charge instabilities and to obtain a strong gain at microwave and THz frequencies in semiconductor supe…
