Analog modulation of semiconductor laser
Bíreš, Pavol ; Steinbauer, Miloslav (oponent) ; Drexler, Petr (vedoucí práce)
In my project I designed laser diode driver. The project was designed in program called Eagle and in this program was made scheme and printed circuit board too. Design of laser diode driver scheme was created on the base knowledge of the properties, functions and conditions of laser diode spectrum. Scheme fulfills conditions of laser diodes power supply and requests for their connection. I made printed circuit board of laser diode driver, on which I set components and successfully get it to run. After that was my work to measure properties of driver. By measuring I verified parameters of designed circuit.

Numerical method for computing electromagnetic field
Bíreš, Pavol ; Čížek, Martin (oponent) ; Rozman, Jiří (vedoucí práce)
The aim of the work is to study the electromagnetic field theory, finite element method and the interaction of electromagnetic field with tissues. Gained knowledge is then used to calculate spreading of the electromagnetic field in the microwave field and to create a temperature profile of spreading the electromagnetic fields in human tissue. The finite element method was implemented in the Matlab programming environment, where the 1D model was created in the frequency and time domain and a simple 2D model created in time domain. The program was developed to analyze spreading electromagnetic wave. Another part of work was done in the programming environment of COMSOL Multiphysics. In this case was the human leg exposed to electromagnetic fields. The analysis determined the changes of temperature in these biological tissues for six minutes.
