| 发明名称 | Gyrotropic metamaterial structure | ||
| 摘要 | A gyrotropic metamaterial structure that include a plurality of chiral metamaterials forming one or more pairs of dipole structures. A plurality of lumped circuits are positioned between the one or more pairs of dipole structures. The lumped circuits have a plurality of subwavelengths antennas that are combined to change the polarization states of an incident polarized wave by producing Faraday-like rotation allowing for nomeciprocal propagation of the incident polarized wave. | ||

| 主权项 | 1. A gyrotropic metamaterial structure comprising: a plurality of chiral metamaterials forming one or more pairs of dipole structures; and a plurality of lumped circuits positioned between the one or more pairs of dipole structures, the lumped circuits having a plurality of antennas that are combined to change the polarization states of an incident polarized wave by producing Faraday-like rotation allowing for nonreciprocal propagation of the incident polarized wave, wherein the lumped circuits comprise an amplifier structure that amplifies the power received by the incident polarized wave and provides a selected number of the one or pairs of dipole structures while isolating the remaining one or more pairs of dipole structures. | ||
