Measurement of sound power and absorption in reverberation chambers using energy density.
Reverberation chamber measurements typically rely upon spatially averaged squared pressure for the calculation of sound absorption, sound power, and other acoustic values. While a reverberation chamber can provide an approximately diffuse sound field, variations in sound pressure consistently produce uncertainty in measurement results. This paper explores the benefits of using total energy dens...
متن کاملReverberation chambers – design and application for EMC
Reverberation chambers are a promising EMC test environment which has several advantages. The set-up and design of reverberation chambers are discussed in the first part of the paper. The second part deals with their application for EMC. Several performance and comparison tests are presented and discussed which show a good reliability and reproducibility of the reverberation chamber as a test e...
متن کاملLossy chaotic electromagnetic reverberation chambers: Universal statistical behavior of the vectorial field.
The effective Hamiltonian formalism is extended to vectorial electromagnetic waves in order to describe statistical properties of the field in reverberation chambers. The latter are commonly used in electromagnetic compatibility tests. As a first step, the distribution of wave intensities in chaotic systems with varying opening in the weak coupling limit for scalar quantum waves is derived by m...
متن کاملOverview of LTE MIMO OTA Throughput Testing in Reverberation Chambers
It is not possible to do direct tests to find the best LTE multi-antenna configuration for optimizing antenna diversity gain, antenna MIMO capacity or device throughput with the traditional antenna measurement method, i.e. an anechoic chamber. Of the two alternatives for making direct measurements, i.e. drive tests and the reverberation chamber, the reverberation chamber offers many advantages....
متن کاملPlane Wave Integral Representation for Fields in Reverberation Chambers
A plane wave integral representation is presented for well-stirred fields in a reverberation chamber. The representation automatically satisfies Maxwell’s equations in a source-free region and the statistical properties of the fields are introduced through the angular spectrum, which is taken to be a random variable. Starting with fairly simple and physically appropriate assumptions for the ang...
