Semiconductor diode modelling
Pacholík, Vladimír ; Wilfert, Otakar (referee) ; Pokorný, Michal (advisor)
This project is about phenomena, which proceed in semiconductor, eventually on semiconductor junction, including equations and relatives necessary for modeling simply semiconductor PN diode, Gunn diode and Schottky diode. Further including short way, how to use this equations and how simulate this diode in COMSOL Multiphysics and Tiber CAD software. Products of modeling are data in charts form. This charts giving basic idea about charge carriers, electrostatic potential and I-V characteristic.

Experimental tags for UHF RFID applications
Pacholík, Vladimír ; Holek, Karel (referee) ; Lukeš, Zbyněk (advisor)
This thesis deals with RFID tags design. It comprises an overview of the RDIF technology while focusing upon the passive tags in UHF band. The CST Microwave studio software has been used for draft simulations. The resulting tags have been subjected to parameter measuring – the reflection coefficient, the minimum capacity needed to switch on the tag, the maximum reading distance. The influence of the proximity of metal objects and other materials has also been examined.
