Behavioral models of active elements with possibility of independent multi-parameter control
Novotný, Jakub ; Hruboš, Zdeněk (referee) ; Šotner, Roman (advisor)
This thesis is focused on behavioral modelling of active elements with independent multi-parameter electronic control using comercially available components. In a first part of the thesis, CVDIBA, CVDOBA, CVCC and OC elements are discussed. The functionality is verified by simulations using OrCAD PSpice. Used components are diamond transistor OPA860, variable gain amplifier LMH6505, differencing amplifier AD830, low distortion differential driver AD8138, current conveyor EL2082 and current mode four quadrant multiplier EL4083. Four active elements are further built on PCB and measured. Some applications like low pass filter, high pass filter, all pass filter and reconfigurable filter.

Reconfigurabe Waveguide Divider
Cupal, Miroslav
The design and implementation of the textile integrated waveguide (TIW) switch for ISM band is presented. The traveling electromagnetic wave is controlled by conductive posts with a circular slot. PIN diodes are used for switching electromagnetic wave to two directions. The simulations results are presented as parametric analysis.
