Surface plasmon polaritons on the surfaces of metal films possess interesting properties. Surface plasmon polariton has the dispersion relation and is a plane propagating surface mode. In contrast, localized surface plasmons (also called electromagnetic surface shape resonances) are confined to curved metal objects. They are characterized by discrete, complex frequencies, which depend on the size and shape of the object to which the surface plasmon is confined, and by its dielectric function. Localized surface plasmons can be resonantly excited with light of appropriate frequency (and polarization) irrespective of the wave vector of the exciting light The idea of two-dimensional surface polariton optics has been proposed and realized experimentally, resulting in the development of optical elements for surface polaritons that allow manipulating and directing SPP beams in the same way as optical beams are directed in three dimensions. Different types of SPP behaviour on rough surfaces, such as scattering, reflection, interference, backscattering, and localization is analyzed, and related theoretical models are presented. Here in this work there is theoretical study of surface excitation in presence of magnetic field on different compounds and results thus obtained is of great application to current world technologies.
