| Abstract | ||
| Abstract In this research we choose the design of Dipole nanoantenna with the adoption of finite difference time domain method. The design result of 0.55μm optical antenna and its performance are presented. The optimal parameters are: [Gap=(10, 15, 20, 25, 30)nm & Length=(200, 240, 280, 320, 360)nm]. The influence of the geometrical parameters (gap dimension , nanoantenna length) on the antenna field enhancement and spectral response is discussed. We found the field enhancement be bigger when the gap be very small at dipole nanoantenna, where in the Gap=10nm the field enhancement more than in the Gaps (15, 20, 25, 30)nm.
