Near-Field Correlation Measurement and Evaluation of Stationary and Cyclostationary Stochastic Electromagnetic Fields

We present methods for measurement and evaluation of stationary and cyclostationary stochastic electromagnetic fields. The radiated electromagnetic interference (EMI) of electronic circuitry is recorded by two-point measurements of the tangential electric or magnetic field components and by evaluating the field autocorrelation functions and for each pair of field sampling points also the cross correlation functions. In case of digital circuitry clocked by a single clock pulse, the generated EMI is a cyclostationary process where the expectation values of the EMI are periodically time dependent according to the clock frequency and which have to be considered in modeling the EMI.     «
