Silver and Gold Nano Antennas for THz Optical Communication
In this manuscript, Nano dipole antenna is designed and simulated using CST MICRO WAVE STUDIO for THz communication. The design is constructed using the noble metals silver and gold as Nano materials. Dispersion properties of gold and silver materials at THz frequency are presented using Drude, Lorentz and Debye models. It is observed that permittivity of a metal becomes complex at the optical frequency and it is frequency dependent. The variation of real and imaginary parts of permittivity for gold and silver materials is plotted. Further it is observed that silver Nano dipole antenna structure has slightly higher resonating frequency compared to gold Nano dipole antenna. It is also noticed that silver has low losses compared to gold at optical frequencies. Directivity of silver Nano dipole antenna is measured to be6. 739dBi and for gold structure it is 6.438 dBi.
