Network Analyzer Studies of Electromagnetic Cavity Resonators

Studies are described in which equivalent circuits for the Maxwell field equations, considered in a companion paper, are set up on an alternating-current network analyzer. These correspond to several simple electromagnetic cavities for which results are known. Comparisons made between the known theoretical results and field distributions measured from the equivalent circuits are used for verification of the equivalent circuits, for evaluation of the usefulness of present network analyzers in high-frequency-field problems, and for suggestions of desirable features for analyzers constructed especially for the study of field problems.
