Abstract
A possibility of almost perfect phase conjugation on electrically thin nonlinear
sheet/”metasurface” with chiral metaparticles is shown for the normal incidence of the signal wave, using non-degenerate interaction with slightly different frequencies of the incident and phase conjugated waves. Under these conditions, the use of linear and nonlinear Huygens sources for both linear (signal) and nonlinear (phase conjugated) waves ensures zero or very small reflection for both of them.
