Abstract
Numerical simulations are used to verify the detailed structure of long range surface plasmon polaritons (SPP). The behavior of the electromagnetic eigenmodes confined to flat metallo-dielectric interfaces are determined with the help of Maxwells equation. Numerical computation based on finite difference time domain (FDTD) method are uses to determine of the modes to show the excitation of SPP in certain practical setting. Prism-coupling scheme can be used to excite SPPs on the flat surface of a metal slab. The odd and even waves that propagate along the surface of metallic slabs are examples of such long-range SPP. FDTD simulations provides a physical picture of field distributions and energy flow patterns in realistic systems that are generally inaccessible to exact mathematical analysis.
