1. 1. EMC-Optimized Transparency: Reducing Electromagnetic Emissions in Surveillance Camera Domes

   Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

   Författare :Fabian Sondh; Erik Hansson; [2023]
   Nyckelord :Technology and Engineering;

   Sammanfattning : Electromagnetic compatibility (EMC) is a crucial aspect to product development. Companies need to make sure their products live up to the standards that exists around the world. One way of reducing electromagnetic emissions is to shield the product, using some conducting material, for instance, copper. LÄS MER

3. 2. Kretskortskonstruktion

   Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Andreas Lövinger; [2023]
   Nyckelord :Kretskortskonstruktion; EMC; elektromagnetisk strålning;

   Sammanfattning : EMC (electromagnetic compatibility) is an important aspect to consider in circuit boarddesign as a product must not be interfered with or interfere with other products throughelectromagnetic radiation. During the development of a prototype, it is primarily important toachieve functionality, and the EMC aspect may only come into play when the product istransitioning from prototype to finished product.

5. 4. Near Field millimeter Wave Antenna Measurements

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Bharath Manjunatha; [2023]
   Nyckelord :Antenna Pattern; Near field to far field; Planar Scanning; Probe Compensation; Active Antenna; Technology and Engineering;

   Sammanfattning : In the real world, understanding an antenna's radiation pattern is crucial for its proper utilization. Typically, antennas are tested in the far-field region, where the radiation lobes are fully developed and phase errors are less than pi/8. LÄS MER

7. 5. Exploring Near-Field SAR with mmWave Pulsed Coherent Radar

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Elina Yrlid; [2023]
   Nyckelord :SAR; Synthetic Aperture Radar; PCR; pulsed coherent radar; radar; mmWave; millimeter-wave; near-field; 60GHz; Technology and Engineering;

   Sammanfattning : This thesis explores the option to apply Synthetic Aperture Radar (SAR) techniques to image near-field targets utilizing mmWave pulsed coherent radar (PCR). The recent development of mmWave radars has broadened the scope for SAR, but there are few concrete examples explaining and demonstrating the fundamental SAR algorithms from a PCR perspective. LÄS MER
