Design and radiation characteristics of optical antennas

In this thesis, the design of the optical antennas and their radiation properties was investigated. Firstly, the principle of operation of optical antennas, the relation between structure and light and matter, design of various optical antenna designs, calculation of radiation fields was made. These radiation fields were calculated in the analytically using the physical optics integral. These calculations were made for each optical antenna and radiation fields are observed. The MATLAB program was used to examine the radiation fields and calculated the physical optic integral. In this way, the various optical antennas designed in that their performance and their radiating properties were shown and the corresponding drawings were included in this thesis.
