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

    Författare :Gustav Eliasson; [2023]
    Nyckelord :RF Switch; PIN diode; Chip Wire Technology; Wide Bandwidth; High isolation; Single-Pole-Single-Throw; Single-Pole-Double-Throw RF Switch; PIN diode; Chip Wire Technology; Wide Bandwidth; Single-Pole-SingleThrow; Single-Pole-Double-Throw; RF-omkopplare; PIN-diod; Chip Wire Tekonologi; Bredbandig; Hög isolation; Enkelpolig-enkakast; Enkelpolig-dubbelkast;

    Sammanfattning : The ability to control the path a signal takes through microwave circuitry is crucial when designing RF systems. The component that allows for the control of the signal path is called a switch, and it is the microwave component that this thesis will focus on. LÄS MER

  3. 2. GRAPHENE MODIFIED E-TEXTILE : AN INDUSTRY RELEVANT APPROACH OF DOPING AND VISUALISING A FULLY TEXTILE P-N JUNCTION DIODES

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Bilel Meskini; [2023]
    Nyckelord :E-textile; viscose; polyester; graphene; graphene oxide GO; reduced graphene oxide rGO; tannic acid; plasma treatment; electrochemical deposition; doping; semiconductor;

    Sammanfattning : As a wonder material, graphene has been studied in various applications due to its exceptional properties. Recently it has been used in textile to obtain functionalised garments as E-textile. From an industry-relevant perspective, it is essential to introduce a process that could be scaled-up. LÄS MER

  4. 3. Numerical Simulations of Resonant Tunnelling Diodes

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Love Sundström; Alexander Holmström Janeld; [2023]
    Nyckelord :Quantum mechanics; numerical methods; resonant tunnelling diode;

    Sammanfattning : In this thesis, four different numerical techniques are implemented for the purpose of simulating resonant tunnelling diodes (RTDs). The chosen methods were: piecewise constant transfer matrix (TMM-C), piecewise linear transfer matrix (TMM-L), quantum transmitting boundary method (QTBM), and the Crank-Nicolson method (CN).

  5. 4. Tolerans av animerat ljus : Vilken storlek och hastighet är nödvändig för att skapa ett sömlöst och mjukt animerat ljus

    Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Författare :Ebba Olsson; Esther Strömberg; [2023]
    Nyckelord :Animation; Cars; Comfort; Diodes; DMX; Exterior and Interior Lighting; LED; LED-Strip; Programming; Animering; Bilar; Dioder; DMX; Exteriör och interiör belysning; Komfort; LED; LED-list; Programmering;

    Sammanfattning : De senaste 10 åren har utvecklingen av LED öppnat stora möjligheter för kreativa lösningar av belysning. Exempelvis kan färgglad och dynamisk fasadbelysning tillverkas. I denna studie undersöks det hur animerat ljus upplevs och hur det skapas en mjuk och sömlös effekt. LÄS MER

  7. 5. Power and Data Transmission throughOptical Wireless Link with emphasis on Application for a Drone

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Salmanuddin Ahamad Siddavatam; [2023]
    Nyckelord :optical wireless transfer; wireless power and data transfer; wireless power transfer; drone;

    Sammanfattning : In the era of power-hungry mobile devices many astonishing advancements have been made but these advancements consume a lot of power and the lifetime of any such device is until the batterylasts. This limits the capability of these devices, one of the examples of such devices is "Drones". LÄS MER
