    Sammanfattning : Semiconductors are used in many electronic applications, for example diodes, solar cells and transistors. Typically, semiconductors are inorganic materials, such as silicon and gallium arsenide, but lately more research and development has been devoted to organic semiconductors, for example semiconducting polymers.

  3. 12. Leakage Suppression for PCB-Waveguide Interconnects Using Hybrid Metasurfaces

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

    Författare :David Gonzalez Gallardo; [2019]
    Nyckelord :;

    Sammanfattning : A metasurface is a two dimensional periodic structure which possessesmacroscopic equivalent electromagnetic properties such as anisotropy, negativerefractive index and Electromagnetic Band Gaps (EBG). EBGs havebeen used for the design of waveguide lters and gap waveguides. LÄS MER
