Unidirectional plasmonic antennas
Formanová, Veronika ; Hrtoň, Martin (referee) ; Kvapil, Michal (advisor)
This thesis deals with directional V-shaped plasmonic antennas. In the thesis, an analytical model of antenna emission is proposed. The results of analytical computations are compared with results of numerical simulations in Lumerical FDTD Solutions package. Also, the process of fabrication of such antennas by electron beam lithography and measurement of optical properties using Fourier infrared spectroscopy is described and measured antenna resonant spectra are shown. Finally, there is a proposal of an experiment to prove the emission directivity of fabricated V-shaped antennas.

Creation of plasmonic micro- and nanostructures by electron beam lithography
Babocký, Jiří ; Dvořák, Petr (referee) ; Kvapil, Michal (advisor)
This beachelor’s thesis deals with a fabrication of plasmonic antennas using electron beam lithography. First section consists of summary of a technologies that can be used for production of metallic micro and nanostructures on silicon and glass substrate. Second section provides a description of electron beam lithography method and technologies that are used for it. Final part describes experiments, that were done and empiric model describing dependance of dimension of fabricated structures on lithographic parameters.
