Measurements using Optic and RF Waves

Preface

 

 

 

The extent of measurements centered on electromagnetism largely exceeds traditional characterization of the electromagnetic fields. It can apply to domains as varied as nanotechnologies, telecommunications, meteorology, geolocalization, radioastronomy, health, biology, etc.

 

Measurement must follow the evolution of technologies. Note, for example, the strong development of radio and optical techniques. It is necessary to learn how to characterize these waves, which are increasingly powerful and propagate in increasingly complex media. These controlled waves also become a formidable tool for measurement, making it possible to consider high performance measurements giving time, distance, spectroscopic characterization, etc.

 

Regarding the multiplicity of controlled radio transmissions added to the different multiple sources that we call electromagnetic noises, there are naturally, increasingly pressing safety environment requirements, applied as standards and increasingly severe thresholds resulting in the development of more precise metrology in electromagnetism and methods of continuously improved measurements.

 

Measurement has a societal requirement that leads to the establishment and respect of recommendations and standards, which are intended for the information of companies and also to preserve public health. Specialists must encourage the development of a true metrological culture. This culture must give professionals and citizens the ability to properly analyze ...
