What term to find symmetrical foot pattern in poetry that features one stressed syllable followed by two unstressed

An amphibrach is a metrical foot consisting of three syllables with the stress on the middle syllable: unstressed - stressed - unstressed.

For example:

* "aWAY from"

* "beFORE the"

* "the WINDing"

When a poem consistently uses this pattern, it's said to be in amphibrachic meter.
