Abstract

This paper investigates the feasibility of the resonant metalens for the imaging beyond the diffraction limit using a single sensor in the far-field. It is shown that the resonant metalens can be related to the super-resonance phenomenon. We demonstrate that the super-resonance supports the enhancement of the information capacity of an imaging system, which is responsible for the subwavelength imaging of the probed objects by using a single sensor in combination with a broadband illumination. Such imaging concept has its unique advantage of producing real-time data when an object is illuminated by broadband waves, without the harsh requirements such as near-field scanning, mechanical scanning, or antenna arrays. The proposed method is expected to find its applications in nanolithography, detection, sensing, and subwavelength imaging in the near future.

  19. The super-resonance is mathematically that the matrix B=I−k2α(ω)RgG0lens→lens(ω)in Eq. (3) is strongly ill-posed, which means that the ratio σ1σN(i.e., the condition number) is very large, whereσ1is the first singular value (the maximum) of the matrix, and σNis the final (the minimum) singular value.
