Workplace for HF Radiated Immunity Testing
Slach, Petr ; Soldán, Josef (referee) ; Svačina, Jiří (advisor)
This thesis investigates into possibilities of a design of a workplace for device endurance experiments against strong high-frequency electromagnetic field. It deals with testing methods, describes advantages and disadvantages of such methods. It investigates possibiities of testing devices, possible magnitudes of fieldstrenght. One can find in the thesis a review of a way of testing using a high-intensity electromagnetic field. A concept of a construction of a stripline including a practical example is a part of the thesis.

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.
