Webb28 apr. 2024 · Note promising planar SWSs on dielectric substrates [3–9] that exhibit significant slow-wave factor, which allows a decrease in the operating voltage, longitudinal size, and mass of the device. We have developed interdigital and meander-type planar SWSs on dielectric (quartz) substrates that work in the V-band (50–70 GHz) [10–12]. Slowing factor: the ratio of the wave wavelength of a "native" transmission line to the wavelength in a slow-wave structure. The higher the slow-wave factor, the more the transmission line's wavelength is reduced compared to its "normal" wavelength in the chosen dielectric medium. Visa mer This class of circuits are related to "artificial" transmission lines (an artificial transmission line uses lumped inductors and capacitors that obey the telegraphers equations). Note that there are many physical … Visa mer In the case of transmission lines, the onset of a stop band for electromagnetic waves in a periodic structure corresponds to Bragg reflection in crystals.
