Dielectric quality
WebThe dielectric constant (Er) or relative permittivity (Dk) of a PCB material is generally between 3.5 and 5.5. A material’s Er level depends on frequency and will usually drop as the frequency rises. The Dk level changes less on certain PCB materials than on others. WebMar 4, 2024 · In this work, a dielectric metasurface consisting of hollow dielectric nanocuboids, with ultrahigh quality factor, is theoretically proposed and demonstrated. The variation of the hole size of the cuboid allows for the tuning of the resonant anapole mode in the nanoparticles.
