| Term (EN) | propagation coefficient, propagation constant (term deprecated) (USA) (symb.: λ) |
|---|
| Definition (EN) | The limit of the natural logarithm of the ratio of values at a given frequency of a specified component of an electromagnetic field at two points aligned in the direction of propagation of a guided or plane wave or of a wave practically plane in a limited space domain divided by the distance between the two points when this distance tends to zero.
Note. — The propagation coefficient is a complex quantity usually a function of frequency and has the dimension of reciprocal length. |

| Term (SR) | koeficijent prostiranja, konstanta prostiranja (zastarjeli termin) (SAD) (simbol: λ) |

| Definition (SR) | Granična vrijednost prirodnog logaritma odnosa vrijednosti na datoj frekvenciji određenog dijela elektromagnetnog polja u dvije tačke poravnate u pravcu prostiranja vođenog ili ravnog talasa ili gotovo ravnog talasa u domenu ograničenog prostora, podijeljenog rastojanjem između dvije tačke kada ova udaljenost teži nuli.
Napomena — Koeficijent prostiranja je kompleksna veličina obično funkcija frekvencije i ima dimenziju recipročne dužine. |
