Broad-spectrum signal propagation through inhomogeneous medium
Měcháček, Radek ; Drexler, Petr (referee) ; Fiala, Pavel (advisor)
Work is focused on both theoretical knowledge of the electromagnetic field and the specific properties of metamaterials measured. First, be informed about the fundamentals of electromagnetic fields, the issue of periodic structures to the properties required metastructures. Further experimental work is designed to measure the properties of metamaterials. The measurements will be used as harmonic signals and broadband signals in the frequency range 100MHz to 10GHz. In the last part of the proposed work is carried out experimental work and are evaluated some characteristics of the antennas and measurement of the selected sample.
The suppresion of mechanical stress impacts in fiber optic transmission systems
Pavlů, Michal ; Szabó, Zoltán (referee) ; Drexler, Petr (advisor)
This bachelors project deals with the suppresion of mechanical stress impacts in fiber optic transmission systems. Factors that have major influence on the polarization state distortion in optical fiber are discussed. It has been propřed the utilization of orthoconjugate retroreflector (OKR) for the compensation of polarization state degeneration. The theoretical analysis of this method is performed. The OKR method has been experimentally verified in the fiber optic current sensor. On the basis of results which were obtained by experimental verification the experimental results show evidence konvenience of the designed method.
