Part I reviews methods of generating microwaves in the shorter cm and mm region examining their possibilities, technical problems and limitations. It concludes that the spark microwave generator has its part to play in this field. A historical survey of past work on microwave spark generators which has been published by the author in Brit.I.R.E. Journal 13, 1953. p.490 is attached as Appendix I, Part II analyses the theory and evidence in support of the characteristic radiation from a dipole type spark generator. It also examines in detail methods of frequency analysis and spectrum filtering by a large variety of semi-optical and waveguide devices. The Boltzmann interferometer is dealt with exhaustively. Some discussion of available power is also included. Part III describes some technical problems of spark generation and methods of solving them. Experiments are described to test waveguide devices which permit the control of radiated frequency band and result in a source tunable over a 2 to 1 range of frequencies. The established principles can be used to test waveguide components for matching characteristics and filters - in particular wide band filters - for their response and any spurious effects. The range covered extends from 8 mm to 5 cm. Appendix II contains a paper on the theory of a quarter wave transformer filter which is due to appear in "Wireless Engineer", Appendix III dealing with the diffraction of non-monochromatic e.m. waves by a slit and a grating is a reprint from Proc, Phys. Soc, 68B, 1955. p.171.
