Hi lad,
i was not certain so i double checked :
https://en.m.wikipedia.org/wiki/Isotropy
Physics - - Electromagnetics :

An isotropic medium is one such that the permittivity, ε, and permeability, μ, of the medium are uniform in all directions of the medium, the simplest instance being free space.

... if you read this like i do, they do not care to diferentiate "round trip" and "one way" ... and my vocabulary is not good enough to find a word that would fit.
