چکیده
|
Metasurface lenses which could simultaneously focus both surface plasmon polaritons (spps) and transmitted wave are designed. this kind of device is composed of slit antennas and is optimized with the simulated annealing algorithm to realize a single-focus or double-focus lens. interestingly, the focusing of spps is polarization dependent while the focusing of the transmitted wave is immune from the polarization of incident light. the proposed methodology inspire more designs of device steering both surface wave and transmitted wave.
