Harmonic image reconstruction assisted by a nonlinear metmaterial surface

Harmonic image reconstruction assisted by a nonlinear metmaterial surface

We experimentally demonstrate a microwave far-field image reconstruction modality with the transverse resolution exceeding the diffraction limit by using a single layer of highly nonlinear metamaterial. The harmonic fields of the nonlinear metamaterial surface allow the far-field propagation of wave...
