Perfect-lens theory enables metasurface reflectors for subwavelength focusing

HIGHLIGHTS

  • who: Taghvaee Hamidreza from the Faculty University of Nottingham , RD, United Kingdom have published the article: Perfect-Lens Theory Enables Metasurface Reflectors for Subwavelength Focusing, in the Journal: (JOURNAL) of 16/07/2022
  • what: In Sec V, the authors investigate the robustness of focusing. The authors explore the possibility of checking that the reflected fields are the same as the fields created by a point source behind a perfect lens (fields are formed by a slab of a double-negative material with relative permittivity and permeability equal to -1) . In the following, the authors show . . .
