Correlation and Spectral Density Functions in Mode-Stirred Reverberation -- II. Spectral Moments, Sampling, Noise, EMI and Understirring
Luk R. Arnaut, John M. Ladbury
In part I, spectral moments and kurtosis were established as parameters in analytic models of correlation and spectral density functions for dynamic reverberation fields. In this p…
Correlation and Spectral Density Functions in Mode-Stirred Reverberation -- III. Measurements
Luk R. Arnaut, John M. Ladbury
Experimental auto- and cross-correlation functions and their corresponding spectral density functions are extracted from measured sweep data of mode-stirred fields. These are compa…
Correlation and Spectral Density Functions in Mode-Stirred Reverberation -- I. Theory
Luk R. Arnaut
Auto- and cross-spectral density functions for dynamic {random} fields and power are derived. These are based on first- and second-order Padé approximants of correlation functions…
Nonstationary random acoustic and electromagnetic fields as wave diffusion processes
L. R. Arnaut
We investigate the effects of relatively rapid variations of the boundaries of an overmoded cavity on the stochastic properties of its interior acoustic or electromagnetic field. F…
