Waveguide-SIW transitions
Bednarský, Vojtěch ; Láčík, Jaroslav (referee) ; Špůrek, Jan (advisor)
This work deals with the design of waveguide transitions. In this work I describe two usually used types of waveguides and that is classical rectangular waveguide with standardized designation WR-10, which is designed for working frequency 94GHz. The second type will be a waveguide integrated into the substrate called SIW. In the first part, numerical models of waveguides are calculated and transitions are created. Numerical models are simulated in CST Microwave Studio. Transitions are constructed in two types. Horizontal transition and orthogonal transition. The results of the first part are obtained dimensions of parameters from numerical models and S-parameters of transition sets.

Design and implementation of TEM cell
Bednarský, Vojtěch ; Růžek, Václav (referee) ; Dřínovský, Jiří (advisor)
The purpose is to design and make a TEM cell, which may often be referred to in publications as a Crawford chamber, after the inventor. The operating frequency is specified from 100 kHz to 400 MHz and is suitable for a test device of maximum size (0,3(l) x 0,3(w) x 0,1(h)) meters. I will first describe the basic methods of electromagnetic susceptibility testing, and electromagnetic interference measurements, and then mention the issues and motivations for the fabrication of the closed TEM cell. Computer simulations were performed in the numerical computing software CST Microwave Studio. The calculated dimensions were used as a starting point for simulation. Dimensions from the simulation were used for the fabrication of the closed TEM cell, which showed similar results as the results of the simulations.
