Evanescent-to-propagating wave conversion in sub-wavelength metal-strip gratings


Transmitting sub-wavelength information to the far-zone is of great interest for various electromagnetics and optics applications, e.g., for overcoming the diffraction limit in imaging or enabling multiple-input/multiple-output operation in closely spaced antennas. The common phenomenon in these applications is the conversion of evanescent to propagating… (More)
