The Montreal Protocol controls the manufacture and use of substances that deplete the Earth's stratospheric ozone. Amongst the chemicals under regulatory control are two halogenated solvents used widely in the electronics industry: CFC-113 and 1.1.1 trichloroethane. The paper gives the environmental science of ozone depletion and its ecological impact. The properties and uses of the common halogen... View full abstract»

Integrated optoelectronic devices are becoming more important as the demand for low-cost devices for sophisticated applications increases. The paper reviews the techniques of bandgap engineering which can be used to control the characteristics of integrated optoelectronic devices fabricated with III-V semiconductors. In particular, the use of quantum wells as active and passive elements in devices... View full abstract»
The advent of high-speed digital signal processing has revolutionised radio receiver design. The paper describes the design of surveillance receivers based on fast analogue-to-digital conversion and the fast Fourier transform. Several system architectures are discussed and the performance issues which need to be resolved in the design of a receiver are examined. These include bandwidth, dynamic ra... View full abstract»

The paper deals with the future use of the 20/30 GHz satellite communications band, especially with regard to small earth terminals. The 20/30 GHz bands are attractive for private link applications, but are subject to large signal attenuations in the presence of rainfall. Methods to overcome the rain attenuation, known as fade counter-measures, are investigated.<
