    Keywords : Ceramic coating; Dip coating; Radio frequency; Passive RF devices; Quality factor; Keramisk beläggning; Dip-beläggning; Radiofrekvens; Passiva RF-enheter; Kvalitetsfaktor;

    Abstract : The demand for high-performance Radio Frequency (RF) passive devices has been steadily increasing due to the growing complexity and sophistication of wireless communication systems. The Quality factor (Q-factor) is a key parameter for describing the signal losses and the energy efficiency of resonators. READ MORE

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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Haomin Liu; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. Influences of palladium ceramics on valuable metal losses to a PbO-SiO2-Sb2O3 based silver smelting slag.

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Per Kautto; [2020]
    Keywords : palladium ceramics; silver smelting slag; PbO-SiO2-Sb2O3;

    Abstract : Silver and palladium can be found in the so called palladium-ceramics which comes from catalyst production. These valuable metals needs to be recovered from these wastes in order to further increase both the environmental and economic sustainability of our society. READ MORE

  6. 5. Additive manufacturing and radio frequency filters : A case study on 3D-printing processes, postprocessing and silver coating methods

    University essay from KTH/Industriell produktion

    Author : Ana García-Verdugo Zuil; Amanda Herrero Martín; [2020]
    Keywords : Additive manufacturing; radio-frequency filters; post-processing; silver coating; surface roughness; Multi Jet Fusion MJF ; Selective Laser Melting SLM ; Tillsatsstillverkning; radiofrekvensfilter; efterbehandling; silverbeläggning; ytojämnhet; Multi Jet Fusion MJF ; Selective Laser Melting SLM ;

    Abstract : Additive manufacturing (AM) is an attractive way to shorten development time, reduce product weight and allow the manufacturing of more complex products than by conventional manufacturing processes. The problem arises when the previous traditional manufacturing requirements need to be fulfilled by AM as well as the volume production capability. READ MORE
