    Fiber-Coupled Fabry-Pérot Interferometric Sensor: Analysis And Modelling
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Skalský, Michal
    This paper presents a theoretical analysis of the Fabry-Pérot interferometric sensor utilizingan extrinsic fiber-optic cavity. Its behavior is modelled and simulated for various conditions,showing the key properties of the different sensor’s setups. The simple single-mode sensing tip andthe GRIN collimator are compared. Further, new kind of sensing head is proposed exhibiting aninverse reflectivity and enabling a theoretical resolution less than 1 pm.

    Comparison Of Measurement Methods For Characterization Of 3d Printed Lowloss Artificial Dielectric Substrate Based On Cross Unit Cell
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Kaděra, Petr
    This paper deals with the effective complex permittivity determination of low-loss 3Dprinted artificial dielectric substrate based on a cross unit cell. The two resonators working withTE011 and TM010 modes suitable for a uniaxial anisotropy determination are compared with thetransmission / reflection waveguide method. To evaluate the methods’ performance, the eigenmodeanalysis is carried out to provide precise reference values.

    Pedestrian Detector Domain Shift Robustness Evaluation, And Domain Shift Error Mitigation Proposal
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Zemčík, Tomáš
    This paper evaluates daytime to nighttime traffic image domain shift on Faster R-CNNand SSD based pedestrian and cyclist detectors. Daytime image trained detectors are applied on anewly compiled nighttime image dataset and their performance is evaluated against detectors trainedon both daytime and nighttime images. Faster R-CNN based detectors proved relatively robust, butstill clearly inferior to the models trained on nighttime images, the SSD based model proved noncompetitive.Approaches to the domain shift deterioration mitigation were proposed and future workoutlined.

    Characterization Of Aln Nanolayers Deposited On A Surface Of Hopg By Pe-Ald
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Dallaev, Rashid
    In this study plasma-enhanced atomic layer deposition process of AlN has been performedwith the purpose to test the expediency of highly oriented pyrolytic graphite (HOPG) to serve as asubstrate in such process. The obtained samples were thoroughly analyzed using various analyticaltechniques. Atomic force microscopy was employed for studying topographic and morphologicalfeatures of the surface; x-ray photoelectron spectroscopy (XPS) analysis supported by second ionmassspectrometry method (SIMS) has been conducted on the obtained sample to investigate thechemical nature of the deposited films as well as elemental distribution. Temperature stability ofHOPG makes it a suitable substrate for preparation of AlN films, being a bottom contact for furthertesting of the films electrical properties. The data gathered from the aforementioned techniques haveindicated that HOPG is a viable choice for AlN ALD process.

    Electrohydrodynamic Model Of Electron Microscope
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Mačák, Martin
    This work presents a complex multiphysics model of an electron microscope in ANSYSFluent software. A custom electromagnetic model was used to describe the relativistic transport ofelectrons. The model consisted of a description of an electromagnetic field, relativistic transport ofcharged particles and interactions between charged particles and solid materials. Presented resultssuggest, that the custom model can be coupled with the CFD module, which results in a possibilityof coupled simultaneous simulations of hydrodynamics, electromagnetics, and a transport of chargedparticles.
