Near-field enhancement and imaging in double planar polariton-resonant structures
Near-field enhancement and imaging in double planar polariton-resonant structures
It is shown that a system of two coupled planar material sheets possessing surface mode (polariton) resonances can be used for the purpose of evanescent field restoration and, thus, for the sub-wavelength near-field imaging. The sheets are placed in free space so that they are parallel and separated by a …
