antimetric

(not comparable)The converse of symmetric in electrical network theory, especially filter theory. A network where the input and output image impedances are the dual, or inverse, of each other as opposed to symmetric networks where they are equal.

A Butterworth filter with an odd number of elements is symmetric while one with an even number of elements is antimetric.

(not comparable)In mechanics, relating to a pair of forces, a pair of oscillations or other motion acting in the opposite direction to symmetric.
