Ordinarily, these fibers behave as a linear medium.

Video tape is essentially a linear medium, but video discs can be explored through a variety of pathways.

"Also, it's a linear medium: stick it in, press play, that's all you get."

For a linear medium, only the first term of this equation is significant and the polarization varies linearly with the electric field.

Since light is an oscillation it is not affected by travelling through static electric or magnetic fields in a linear medium such as a vacuum.

In traditional engraving, which is a purely linear medium, the impression of half-tones was created by making many very thin parallel lines, a technique called hatching.

Contrast this with efforts to use a linear medium such as videotape interactively.

It may be written in the same way, but would not necessarily need to be, to be considered a linear medium.

Any two different waves can sail through each other at an angle, without interacting, in a linear medium.

The linear, non-dispersive medium is the type most amenable to our mathematics, enabling us to derive and understand many things about it.
