Abstract :
This paper describes simple reflection coefficient standards for use with the circular TE/sub 01/ mode. They consist of circular irises inserted directly into the flange connection of a "matched" termination. The reflection coefficient of an iris is formulated exactly and then evaluated to any desired degree of approximation with a digital computer. The results of a 30-mode approximation are presented and shown to agree with 24 GHz measurements of the modulus and phase of /spl rho/ of 7 irises to within about 0.008 relative units and 0.02 radians, respectively.
