In this paper, the first experimental demonstration of coherent directive and polarized wavefront generation within a reverberation chamber is presented. This feature is possible with the use of a time-reversal electromagnetic chamber, a concept that we previously introduced which mainly relies on the use of time-reversal techniques in a highly reverberating medium. The rationale for developing such a system is to provide the control of a field distribution in time and space without any mechanical move of neither sources nor an equipment under test while preserving the high-intensity field levels achieved with reverberation chambers.
