Sub-Wavelength Focusing in Inhomogeneous Media with a Metasurface Near Field Plate
Overcoming the diffraction limit, which enables focusing much less than the wavelength, requires tailoring the evanescent spectrum of an aperture’s field distribution. We model and simulate a corrugated near field plate, which can generate a sub-wavelength focus in inhomogeneous background...
