7、his Foreword is not a part of IEEE Std 147-1979, Standard Definitions of Terms for Waveguide Components.) The Waveguide Standards Committee of the Microwave Theory and Techniques Society (MTT) was formed in 1968 following direction from the IEEE to associate this work with the appropriate technical
8、group. The committee membership was drawn partly from the original Antenna and Waveguide Standards Committee, and the work contained herein is based on the considerable effort and background provided by that committee. This standard presents definition of components in waveguide usage. These compone
9、nts are considered to be linear, passive, and reciprocal unless otherwise specified in the definitions. The definitions included were drawn from the Institute of Radio Engineers document No 53 IRE 2.S1- 1953, IRE Standards on Antennas and Waveguides; Definitions of Terms, No 59 IRE 2.S1-1959, IRE St

The present list is not intended to contain all possible component varieties. For example, defini- tions of bends which may be mitered o

The members of the Subcommittee on Definitions of Waveguide Components of the IEEE Micro- wave Theory and Techniques Society who contributed to this standard during 1968-1975 were: D. J.
