Abstract :
The fields covered by the review are: Electromagnetic theory as applicable to wave propagation, theory of wave-guides and components, microwaves in fundamental measurements (such as time and atomic constants), designs of components, measurements, solid state devices and a summary of utilization. Future trends are also indicated. The review (with some exceptions) does not cover the following fields: Antennas, propagation and microwave tubes. In reviewing technical publications, preference is given to such aspects of work which are novel, fundamental or are of controversial nature or are likely to influence future trends; where appropriate, criticism of the work is given.
