Metallic nanoparticles display unique properties that are quite different from those of individual atoms. In reality, the optical properties of the nanoparticles strongly depend on its shape. We present the electrostatic approach to evaluate scattering and absorption of different shaped nanoparticles under an oscillating electric dipole moment. For numerical simulations, we present the depolarization factor of the elliptical and cubical nanoparticles with a Drude dielectric profile. Numerical results illustrate that the geometry factor, the host dielectric constant and the damping coefficient can affect the scattering and absorption spectrum significantly. To meet the requirements of optical devices, such a tunable structure can be used to design optical sensors, modulators and detectors.
