Non-intrusive probing techniques for the characterisation of environments for electromagnetic measurements

An optically modulated scattering technique for the measurement of electromagnetic field inside conducting enclosures is described and applied to electromagnetic compatibility (EMC) and associated fields. The scatterers are tuned dipoles and loops, so as to measure both the electric and magnetic field at low level. The monostatic system employed is flexible and convenient to measure any component of the field. The measurement results are shown to be of high repeatability and accuracy
