  1. 1. "Resonance frequency, Q-factor, coupling of a cylindrical cavity and the effect on graphite from an alternating electric field".

    Kandidat-uppsats, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Jakob Gölén; Simon Persson; [2021]
    Nyckelord :Q-factor; Resonance frequency; Cavity; Microwaves; Heating; Q-faktor; Resonansfrekvens; Kavitet; Mikrovågor; Uppvärmning;

    Sammanfattning : The purpose of this project was to investigate a cylindrical cavity resonator and use microwaves to heat up a material in the cavity. This was done by measuring the Q-factor and the resonance frequency of the cavity, both with and without material inside. LÄS MER

  3. 2. Graphene-based Crack-Free Ceramic Coatings for High-Performance Passive RF Devices

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

    Författare :Haomin Liu; [2021]
    Nyckelord :;

    Sammanfattning : Dielectric resonators coated with highly conductive metallic layers are widely used in radio frequency (RF) applications. The quality factor (Q-factor) of resonators is a key figure-of-merit that describes the loss and the energy efficiency of the resonators. LÄS MER

  4. 3. Microeletromechanical Systems for Tunable Ring Resonators on a Silicon Platform

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

    Författare :Chris Phong Van Nguyen; [2021]
    Nyckelord :Integrated photonics; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ring Resonator; Telecommunications; Integrerad fotonik; Silicon Photonics; MEMS; Silicon Photonic MEMS; Ringresonator; Telekommunikation;

    Sammanfattning : Advancements in photonic integrated circuits, so-called PICs, have progressed fast in the last decades. More complex PICs are getting developed, which are promising in possibly offering advantages like low power consumption and high-performance computing. Re-programmable photonic FPGAs are one of these candidates. LÄS MER
