Description

Electromagnetic Field Standards and Exposure Systems addresses the need to establish measurement standards for electromagnetic fields for the conditions and accuracy of results.

This book provides a review of fundamental properties of electromagnetic fields and the simple antennas that can generate and receive such fields. The main focus of this book is dedicated to the analysis of the accuracy of measurements and field standards using a range of radiating structures.

Electromagnetic Field Standards and Exposure Systems covers the broader fields of measurements in telecommunications, radio navigation, radio astronomy, bioscience, and free ranging EM radiation and helps to develop the following measurement standards;

  • proper calibration of the measuring instrument
  • external environmental factors that affect accuracy
  • competence and training of the instrument operator
