Propagation characteristics of an electromagnetic wave through parallel plane waveguide filled with nanoparticles is studied. The dispersion relation reveals two modes, a surface plasmon like mode for ω≥ω_pe √3 pe ω≤ω , (ω is electromagnetic wave frequency and ω_pe is electron plasma frequency of nanoparticles) and another normal electromagnetic mode for ω≥ω_pe √3 . The plasmon like mode is sensitive to plate separation and the excitation frequency is higher for smaller plate separation. The cutoff frequency of electromagnetic mode can be varied by changing the concentration or size of the nanoparticles and also the plate separation.
