Thin-film systems
Kuchařík, Jan ; Máca, Josef (referee) ; Zatloukal, Miroslav (advisor)
This bachelor thesis concerns to create of thin films on various types of substrates. In the theoretical parts is an overview of the formation of thin films using several techniques. The thesis contains an overview of substrate cleaning processes before the deposition of layer plates and tools for evaluating their properties. Finally, the masking method is discussed. In the experimental part, the acquaintance with the NP - 12 sputtering device and the production of samples took place. The adhesion of the produced samples was evaluated. Electrolysis of samples with titanium coated followed. Finally, the silicon substrate was masked.

Vacuum technologies for creating thin-film systems
Kuchařík, Jan ; Šafl, Pavel (referee) ; Zatloukal, Miroslav (advisor)
The theoretical part of this theses deals with the formation of thin films by vacuum methods. It is a chemical and physical deposition from the gas phase in vacuum environment. Chemical deposition takes place at elevated temperatures, which accelerate reactions. Physical deposition is most often only condensation of vapors of evaporated material. Physical methods are vacuum evaporation, as well as cathodic, ionic, reactive and magnetron sputtering. The formation of thin layers takes place according to 3 known mechanisms. Substrates must be surface treated before the deposition process. The quality of thin films is examined from several perspectives. The practical part is devoted to the production of a thin-film system of copper and tin on a glass substrate. These layers are separated by three different barrier metals. Subsequently, the prepared samples were exposed to thermal stress and were monitored by electron microscope. Diffusion processes at the thin film interface were compared.

Calculus of variation in Physics and Geometry
Kuchařík, Jan ; Krýsl, Svatopluk (advisor) ; Scholtz, Martin (referee)
Název práce: Variační počet ve fyzice Autor: Jan Kuchařík Katedra / Ústav: Matematický ústav UK Vedoucí bakalářské práce: RNDr. Svatopluk Krýsl, Ph.D. Abstrakt: Ve své práci shrnuji některá základní použití variačního počtu v praktických aplikacích. Odvozuju zde nezbytný matematický aparát. Zavádím pojem matematického funkcionálu a jeho extremalizaci, odvozuji Euler-Lagrangeovu rovnici a její důsledek - Beltramiho identitu; dále se věnuji odvození metody řešení izoperimetrických úloh, která zobecňuje metodu Lagrangeových multiplikátorů. Ačkoliv se v práci vyskytují řešené úlohy nejrůznějšího typu, zaměřuju se na čtyři hlavní oblasti: Fermatův princip, Hamiltonův princip nejmenší akce, isoperimetrické úlohy a hledání geodetik. Title: Variational calculus in physics Author: Jan Kuchařík Department: Supervisor: RNDr. Svatopluk Krýsl, Ph.D. Abstract: In my research work, I try to collect some basic usage of variational calculus in practical applications. I derive all the necessary mathematical tools. I explain what is a fuctional and what it means to extremalize it, I derive Euler- Lagrange equation and its corollary - Beltrami identity. I also try to derive a method for solving isoperimetric problems which generalizes the one of the Lagrange multipliers. Although there is a variety of several different...

Analytical solution of diffraction by planar periodic structures
Kuchařík, Jan ; Antoš, Roman (advisor) ; Ostatnický, Tomáš (referee)
In my research work, I study diffraction by planar periodic structures (diffraction grating). In the first chapter, I try to familiarize the importance of diffraction gratings in spectroscopy. The second chapter explains the basic principle of diffraction without involving difficult mathematical tools. In the third chapter, I deduce Fourier modal method from Maxwell equations, a modern mathematical approach used for calculating the electromagnetic response of diffraction. The most important part of my work consists of the fourth and fifth chapter. At first, I try to utilize Fourier modal method for deriving formulas involving just 0th and (-1)st diffraction orders. Because of the unreasonable difficulty of uncovered formulas, I decided to consider only a special case - so-called Littrow configuration, in which the solution can be superposed from symmetric and antisymmetric couples of rays. I further develop so-called Local modal method - very inaccurate, but mathematically fairly simple, and discuss its physical limitations. Whole work is finished by the sixth chapter, which compares accurate computations gained from simulation and derived analytical formulas for both methods.
