Thermal analysis of Gunn diode
Chára, Pavel ; Lukeš, Zbyněk (referee) ; Pokorný, Michal (advisor)
The aim of bachelor’s project has been thermal analysis of Gunn diode. Gunn diode model involving thermal effects was analyzed in COMSOL Multiphysics. Another task was to design a suitable heat sink for diode and its proper function to verify simulations.
Planar transmission line on semiconductro substrate
Chára, Pavel ; Harwot, Ondřej (referee) ; Pokorný, Michal (advisor)
The aim of this thesis is to acquaint with the various types of the planar transmission lines and discuss their properties. Subsequently, the development of the real models of selected lines and verification their properties by simulations using COMSOL Multiphysics. The second part deals with the modeling of the semiconductor substrate, which replacing the dielectric substrate used for the transmission lines in the first part. The final part deals with the verification of calculation results in a specialized program TiberCAD.
