Microwaves - a review of recent applications and developments

Microwaves can be defined as the happy hunting ground of microwave engineers. Microwave engineers form a community even when they branch out and make contributions, for example, in optical or acoustic waveguides. Such developments are reported in microwave publications, at least until they separate out or attach themselves to other disciplines. Thus, technology transfer takes place. However, the majority of applications to be reviewed depend on radiation at frequencies in the true microwave range, that is, at frequencies generally around 1000 to 10 000 million cycles per second (1 to 10 GHz)
