The Susceptance of a Thin Iris in Circular Wave Guide with the TM01 Mode Incident

Abstract

Certain wave-guide boundary value problems can be formulated in terms of lumped-constant circuits and distributed-constant transmission lines. Equivalent circuit voltages and currents can be introduced as measures of the transverse electric and magnetic fields. Making use of these concepts and Schwinger's integral equation method, the susceptance of a thin circular iris in circular cylindrical wave guide with the TM01 mode incident is discussed and calculated. Results are compared with experimental data.

Model of Finite Inhomogeneous Cavity Chain and Approximate Methods of Its Analysis

“…and m L = 500 for the M-J and M-M cases. The correctness of the calculation results is confirmed by comparison with the experimental results[40].Bellow we will be use the M-J representation with m N = 2 and m L = 500. Analysis of more complicated system (wave diffrac-4.2 cm, aperture radius a  1.5 cm) shows that chosen values of the number of functions give acceptable accuracy of field calculation too.…”

Diffraction Theory

“…First of all we have to mention in this connection two reports by Bethe (1943a, b). Related work is due to Bernier (de Broglie 1948, p. 77), Casimir (1951), Chu and Hansen (1949), Dunning and Fellers (1951) ' Ginzton and Goodwin (1950), Klein (1951), Levin (1948 b), Marcuvitz (1951a), Stevenson (1948), and Teichmann and Wigner (1953. The effective permeability of an array of thin conducting discs was investigated by Estrin (1950) and the problems discussed by Ashour (1950Ashour ( , 1952 have also a bearing on our subject.…”
