Double Negative Media Based on Magnetic Metamaterials and Semiconductors for the Microwave Frequency Range

The results of theoretical study and numerical simulations in the MaxLLG software package of ferromagnetic metamaterials with metallic (non-magnetic) inclusions, as well as bigyrotropic media with properties of a ferromagnetic semiconductor, are presented. The possibility of obtaining double-negative media from such materials, where a backward electromagnetic wave exists at microwave frequencies, is demonstrated.
