1. 1. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Franz Wikner; [2024]
   Nyckelord :Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

   Sammanfattning : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

   Sammanfattning : Sub-band full duplex is a new communication scheme technology, where a single frequency band is partitioned into sub-bands for downlink (DL) and up-link(UL) transmissions, and both can take place simultaneously. The idea behind the sub-band full duplex development is to improve the throughput, and coverage and reduce the latency of the UL communication by allowing the UL reception during the DL transmission.

   Sammanfattning : This thesis deals with wireless power transfer from an external source to embedded small devices (such as for conditioning monitoring, control etc.) located at different distances from the source. The proposed designs can be used in a variety of applications, including mobile phones, electric cars, unmanned aerial vehicles, robots, etc. LÄS MER

7. 5. Anti-Reflective Coatings for 3D Printed Quasi-Optical Lenses: Experiments, Simulations, Verification, and Optimization

   Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

   Författare :Christina Ashok; [2022]
   Nyckelord :;

   Sammanfattning : This thesis aims to see how well anti-reflective coatings created for dense material millimeter wave integrated lens work and to validate observations using electromagnetic simulation. The dielectric material was chosen for lens fabrication because it allows for high power transfer capability via the lens and allows the production of affordable and compact-size lenses. LÄS MER
