IEEE 457 – IEEE Standard Definitions of Terms for Nonlinear, Active, and Nonreciprocal Waveguide Components
New IEEE Standard – Inactive-Withdrawn.This standard presents definitions of terms for non-linear, active, and non-reciprocal waveguide components. It is a companion to two other published standards, Definitions of Fundamental Waveguide Terms, IEEE Std 146-1980 and Definitions of Terms for Waveguide Components, IEEE Std 147-1979.The latter covers linear and passive waveguide components.
