  • sagedus, millest allpool muutub lainejuhi levimistegur konkreetse režiimi jaoks reaalseks, nii et selles režiimis ei ole oluline levimine enam võimalik
  • frequency below which the propagation constant of a waveguide becomes real for a specific mode, so that no significant propagation in that mode is possible
lainejuhirežiimi piirsagedus
Usage examples
  • Lainejuhirežiimi piirsagedus on lävi, millest allpool ei saa konkreetne elektromagnetiline olek/režiim levida läbi lainejuhi, mistõttu signaal pigem nõrgeneb kui levib. Igal lainejuhi olekul/režiimil on oma unikaalne sagedus, mille määravad lainejuhi mõõtmed ja valguse kiirus keskkonnas.
cut-off frequency of a waveguide mode
Usage examples
  • The cut-off frequency of a waveguide mode is the threshold below which a specific electromagnetic mode cannot propagate through a waveguide, causing the signal to attenuate rather than travel. Each waveguide mode has its own unique, determined by the physical dimensions of the waveguide and the speed of light within the medium.
