Statistical analysis of audible noise generated by AC corona discharge from single corona sources
High Voltage, 2018 Time-domain waveforms of sound pressure pulses generated by alternate current (AC) corona discharge from single corona sources are measured. The pulse amplitude and time interval of sound pressure pulses in positive and negative half cycles are analysed ...

Near-field measurement of continuously modulated fields employing the time-harmonic near- to far-field transformation [PDF]
Advances in Radio Science, 2019 Near-field far-field transformations (NFFFTs) are commonly performed for time-harmonic fields. Considering arbitrary in-situ measurement scenarios with given transmission signals, time-varying aspects of modulated signals have to be taken into ...
