Broadband superoscillation brings a wave into perfect three-dimensional focus

AMH Wong, GV Eleftheriades - Physical Review B, 2017 - APS
The fundamental properties of a wave precludes it from being localized to subwavelength
distances in all dimensions of the wave's existence. The inability to focus electromagnetic …

Superoscillations without sidebands: power-efficient sub-diffraction imaging with propagating waves

AMH Wong, GV Eleftheriades - Scientific Reports, 2015 - nature.com
A superoscillation wave is a special superposition of propagating electromagnetic (EM)
waves which varies with sub-diffraction resolution inside a fixed region. This special property …

Super-resolution without evanescent waves
