Increasing of Delivered Power in a V-groove Surface

Abstract: In this letter, we presented the dependence of the propagation constants of channel plasmon polarition modes in a V- groove shaped with the geometric parameters of structure, namely the angle of the groove and radius of the tip. The wave numbers of Channel Plasmon Polarition modes with increasing of the angle and radius of the groove bottom is reduced. By studying the distribution of the field and the effective refractive index, we will show that the field confinement is at the end of the groove. Reflection coefficient of the groove height is achieved. By reducing the reflection coefficient, we will increase the delivered power. The maximum amount of delivered power for a Channel Plasmon Polarition waveguide with a height of 182/5nm, the angle 15/8 degree and radius of the tip of the groove 0/5nm is achieved one hundred percent. The propagation length and the effective refractive index are achieved 299µm and 1/6, respectively. We have demonstrated well-confined CPP guiding at 500Thz. With this structure we have prevented from the radiation of the field in to out of the groove. In this paper, we proposed and analyzed this structure by CST Microwav
