Analysis and Design of Nanoantenna Arrays
, M.Sc. Thesis Sharif University of Technology ; Akbari, Mahmood (Supervisor)
Abstract
If the size of the conventional telecommunication antennas -that are widely used in transmitting broadcasted radio and TV messages- is reduced by a nanometer size these antennas can be used at optical frequencies. Dimensions of these optical nanoantennas -that made of nanoparticles with highly permittivity- can be smaller than half of the wavelength. Based on this capability, optical nanoantennas have some important applications such as optical communication, photovoltaic devices, non-classical light, and optical sensing. After studying on optical nanoantennas and their features, in this project, we present distinctions between optical NAs and MW antennas and then investigate about different...
Design of Optimum Nanoantenna Arrays for Detection Applications
, Ph.D. Dissertation Sharif University of Technology ; Rashidian, Bijan (Supervisor) ; Shahmansouri, Afsaneh (Co-Supervisor)
Abstract
The main goal of this thesis is introducing a method to design optimum nanoantenna arrays for detection applications. The proposed method is based on the multiple-scattering T-matrix in connection with the Ewald method. The formulation is systematic, quite general, easily traceable, and fast. Its high speed of analysis makes it well suited to design optimizations.In particular, we calculate multiple-scattering terms of the T-matrix formulation with the Ewald method. To the best of our knowledge no report on derivation of the T-matrix of a 3D (or even 2D) periodic array from the T-matrix of the isolated element, based on Ewald method has been reported before.Finally, a software has been...
