A Global Sensitivity Analysis Study with More Parameters in Undermoded Reverberation Chambers

Abstract

An improved global sensitivity analysis (SA) study by means of Sobol’ indices was performed in this work to investigate the influence of measurement uncertainties on an adequately chosen quantity, which describes the field distribution in the stochastic environment of reverberation chambers (RC). A kriging metamodel is utilized to substitute the computationally expensive full-wave simulation model of a certain RC. This black-box approach provides an efficient apparatus for the stirring and chamber design process.
