  • lainejuhi levimisrežiimi lainepikkus, mis on kahe põiktasandi vaheline kaugus, mille korral samade väljakomponentide faasid erinevad 2π võrra
  • wavelength of a propagation mode of a waveguide is the distance between two transverse planes at which the phases of the same field components differ by 2π
lainejuhi piirlainepikkus preferred
Usage examples
  • Lainejuhi piirlainepikkus λg on kaugus lainejuhis leviva laine kahe võrdse faasitasandi vahel. Kuna elektromagnetlained põrkavad tagasi nurga all, mitte ei liigu sirgjooneliselt, on λg alati pikem kui vaba lainepikkus λ0.

waveguide wavelength
Usage examples
  • A waveguide wavelength (λg) is the physical distance between two equal phase planes of a wave propagating inside a waveguide. Because electromagnetic waves bounce at an angle rather than traveling in a straight line, (λg) is always longer than the wave's free-space wavelength (λ0).
