Diffractive slit patterns for focusing surface plasmon polaritons.
We propose a design method of diffractive slit patterns for focusing surface plasmon polaritons. A scalar model of surface plasmon polariton excitation and interference is adopted, based on which the design method of diffractive slit patterns is built up. The validity of the proposed scalar model-based design is discussed through the comparison of the simulation results of the scalar model and the rigorous three-dimensional vectorial electromagnetic model using the rigorous coupled wave analysis.
