    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.

    Verification Of Modeling Approach By Using Model Of Calculable Capacitor And Determination Of Its Accuracy
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Mancl, Vlastimil
    During the creation of any sort of model the inevitable question about the model correctnessand accuracy, should always be answered. This paper proposes a simple method for modelersto prove their approach to modeling and to determine the accuracy of a simulation. The methodconsists of creating a model of calculable capacitor based on Thompson-Lampard theorem in AnsysElectronics desktop using Maxwell 3D electronics desktop. The model and its parts are described.The expected results are discussed and compared to data obtained from simulation. Problematic ofrounding edges and its influence on simulation accuracy and time is also discussed and shown on twomodels. A part of the paper is a description of how to interpret the Ansys percentage error.

    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.

    Gel Polymer Electrolytes Composed Of Ethyl Methacrylate And Methyl Methacrylate Measured At Higher Temperature
    (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2021) Peterová, Soňa
    This paper is focused on the use of gel polymer electrolytes composed of copolymers ofethyl methacrylate and methyl methacrylate with positive NMC electrode (LiNi0.33Mn0.33CO0.33O2).This article describes the composition of gel polymer electrolyte, the method of preparation anddescription of the NMC electrode. The experiment is based on the measurement of capacity andimpedance at the beginning and at the end of the experiment at room temperature and at highertemperature 40 °C.

    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.
