Magnified imaging based on non-Hermitian nonlocal cylindrical metasurfaces
Magnified imaging based on non-Hermitian nonlocal cylindrical metasurfaces
We show that a cylindrical lensing system composed of two metasurfaces with suitably tailored non-Hermitian (i.e., with distributed gain and loss) and nonlocal (i.e., spatially dispersive) properties can perform magnified imaging with reduced aberrations. More specifically, we analytically derive the idealized surface-impedance values that are required for ``perfect'' magnification and …
