We look forward to meeting you and cordially invite you to the seminar with an accompanying exhibition of products from compan ies operating in the field of high-frequency and microwave technology.\n\n Agenda: \nIntroductory Lecture\n\nThe introductory lecture addresses quant um theory\, which has been with us for many years\, with its origins traci ng back to the early 20th century. Without quantum theory\, we would not b e able to describe the functioning of semiconductor components\, utilize n uclear energy\, or construct lasers. Current quantum technologies are base d on the technological mastery of working with individual objects of the q uantum world – elementary particles\, atoms\, and tangible objects. Thes e technologies truly represent an open door to the future of technology wi th the potential to bring about a fundamental paradigmatic change. Sensors utilizing quantum effects will significantly refine measurements\, quantu m cryptography\, and communication will elevate data processing to a quali tatively higher level\, and the impact of quantum computing on mathematics \, computer science\, and practically all aspects of science and society c annot be overstated.\n\nHigh-Temperature Plasma\n\nHigh-temperature plasma is a fully ionized gas with temperatures ranging from tens to hundreds of millions of degrees. It is primarily studied in scientific research facil ities for the purpose of preparing controlled thermonuclear fusion. Microw aves can be used for contactless measurement of parameters such as plasma temperature or density. This includes both passive measurements – radiom etry\, and active methods – interferometry and reflectometry. The lectur e will cover the principles of measuring plasma temperature and density us ing microwave devices\, block diagrams\, and details of the microwave equi pment used.\n\nElectromagnetic Simulation Tools\n\nElectromagnetic simulat ion tools offer several models for investigating the effect of surface rou ghness of lossy conductors\, but their reliable use remains a challenging task. Unlike the traditional approach\, where the metal surface model is b ased on estimating conductivity and measuring mechanical surface propertie s\, the lecture will describe the direct extraction of surface impedance f rom measured S-parameters of a suitable and well-defined test sample. The entire process will be presented with an emphasis on the reliability and r obustness of the process.\n\nTimepix Pixel Detectors\n\nTimepix pixel dete ctors developed at CERN have proven to be a highly beneficial tool for stu dying particle physics. One of the goals of the facility is to bring these detectors into space. The lecture will describe these detectors and will guide through the development of devices for reading and processing data f rom the detectors\, including pitfalls and challenges.\n\nRadio Frequency and Microwave Sensors\n\nRadio frequency and microwave sensors enable non- invasive monitoring of processes in medical\, biological\, and chemical ap plications. Determining the optimal frequency band from the perspective of the sample to be examined is often unclear in engineering literature. Kno wledge of the molecular structure of matter allows predicting frequency ba nds where the greatest change in the real or imaginary part of permittivit y occurs during biomolecular processes.\n\nAir Traffic Safety\n\nAs the in tensity of air traffic grows\, so do the demands on ensuring its safety. C urrently\, air traffic control and its safety rely on cooperative equipmen t on board aircraft\, specifically transponders of secondary surveillance radar on board. One of the promising independent systems is based on bista tic primary radars\, which are radars with spatially separated receiving a nd transmitting parts. By fusing several bistatic radars\, a multi-bistati c radar system is created. One of its advantages is relatively simple cons truction\, lower cost compared to primary radars\, and deployment variabil ity in terms of covered space. The main disadvantage is very complex signa l processing. The most challenging task of this processing is data associa tion and subsequent target tracking.\n\nAmateur Radio Broadcasting\n\nThe introductory lecture to the discussion evening introduces the hobby known as amateur radio broadcasting. It will cover a wide range of topics - legi slation in the Czech Republic\, frequency bands\, communication methods\, antennas\, radio stations\, propagation\, the ionosphere\, and solar activ ity. The possibility of amateur broadcasting using CB\, PMR radios\, and s o-called shared frequencies will also be mentioned.\n\nBldg: 5\, Novotneho lavka\, Prague\, Czech Republic\, Czech Republic LOCATION:Bldg: 5\, Novotneho lavka\, Prague\, Czech Republic\, Czech Republ ic ORGANIZER:hazdrap@fel.cvut.cz SEQUENCE:11 SUMMARY:REGULAR MEETING OF MICROWAVE TECHNOLOGY ENTHUSIASTS URL;VALUE=URI:https://events.vtools.ieee.org/m/421550 X-ALT-DESC:Description: <br /><p>Take advantage of this exceptional opportu nity to meet with colleagues working in the field\, establish\, renew\, or deepen personal or professional contacts.
