Autonomous power supply with higher EMC requirements
Burian, Jan ; Deneš, Roman (referee) ; Hejátková, Edita (advisor)
This paper deals with design of mechanical and electrical components of autonomous power supply and its testing. It consists of selecting of the materials, draft of shapes and calculations of feed-throughs for the source container to ensure the required electromagnetic characteristics. It also includes the selection of electronic components, comparison of DC-DC converters and filter design with focus on the highest electromagnetic immunity and the lowest electromagnetic emissions.

Computer modeling of implantable antennas
Deneš, Roman ; Kadlec, Petr (referee) ; Raida, Zbyněk (advisor)
The thesis deals with a design of planar antennas and their simulation in the vicinity of a human body. The main goal of this thesis is parametrically analyse different types of planar antennas and find out which one possesses the highest quality in the vicinity of a human body. The design and simulation were made in a software called CST Microwave Studio. Firstly, the attention is paid to the concept of designing and simulation. Further, they are made and tested.

Measurements of electromagnetic interference in anechoic and semi-anechoic chambers
Deneš, Roman ; Růžek, Václav (referee) ; Dřínovský, Jiří (advisor)
This thesis is focused on a detailed analysis of the mechanisms of electromagnetic wave propagation in anechoic chambers. The analysis takes into account the influence of the measurement distance, setup of anechoic chamber and other parameters. Furthermore, the work deals with a validation of both types of anechoic chambers and examines the impact of selected parameters on the measurement results. Based on the theoretical analysis and practical measurement, the comparation between semi and fully anechoic chamber, or a three and ten meter measuring distance was made. This thesis also contains a detailed analysis of sources of the uncertainty.
