  1. 6. Towards a tunable, wide-band acoustic transducer operating in the quantum regime.

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Abel Hugot; [2022]
    Nyckelord :Hybrid quantum systems; Acoustics; Impedance matching; SQUIDs; Hybrida kvantsystem; Akustik; Impedansanpassning; SQUIDs.;

    Sammanfattning : In the past decade we have seen fast development of new quantum technologies that promise to revolutionise communications and computing. Many different routes are explored to physically implement such quantum technologies. Among others, we can mention superconducting circuits, spin-based devices and photonic devices. LÄS MER

  3. 7. Dataset based on volunteer campaign to optimize novel sensor for muscle quality

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Sophia Holmqvist; [2022]
    Nyckelord :sarcopenia; microwaves; medical imaging;

    Sammanfattning : This project had its primary focus on running a campaign to recruit healthy volunteers for a test study involving the utilization of a microwave sensor and ultrasound measurements. The key system used was the Muscle Analyzer System (MAS), which consisted of the Bandstop Filter Sensor (BFS), a microwave sensor transmitting microwaves into the selected medium through transmission and a FieldFox Vector Network Analyzer which was used to transmit these microwaves.

  4. 8. Particle Simulation and Optimization of a Relativistic Magnetron for HPM Applications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Wilhelm Thunberg; [2022]
    Nyckelord :Relativistic Magnetron; FOI Magnetron; TE11; HPM; High Power Microwaves; Particle in cell; MAgic3d;

    Sammanfattning : A relativistic magnetron (RM) is a high-power microwave (HPM) source. The main objective of the RM is to generate directed electromagnetic pulses with high power, which can be used in e.g. HPM weapons and for electromagnetic compatibility testing. LÄS MER

  5. 9. Simulating Microwave Heating for Industrial Processes Using the Finite-Difference Time-Domain Method

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Dante Grenholm; Axel Nilsson; Linus Olofsson; Oskar Pettersson Löfstedt; [2022]
    Nyckelord :Microwave oven; Heating; Simulation; Mikrovågsugn; Uppvärmning; Simulering;

    Sammanfattning : Microwave heating is an efficient way of heating compared to conventional industrial alternatives such as autoclaves, a type of pressure cooker commonly used for curing and sterilisation. One problem that limits the adoption of microwave ovens in industrial processes is uneven heating. LÄS MER

  7. 10. An Analysis on Bluetooth Mesh Networks and its Limits to Practical Use

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Minn Cho; Philipe Granhäll; [2021]
    Nyckelord :IoT; mesh networks; Bluetooth; Raspberry Pi 4; IoT; mesh nätverk; Bluetooth; Raspberry Pi 4;

    Sammanfattning : A mesh network is a technology that is being repopularized and becoming commonly used by the general public. As this increase in use is observed, technologies such as Bluetooth are being adapted to create mesh variants. In this thesis, a Bluetooth mesh network is created and tested using raspberry pi 4’s and the Bluetooth interface, btferret. LÄS MER
