Experimental demonstration of directive pulsed wavefront generation in reverberation chambers

The first experimental demonstration of coherent directive and polarised wave-front generation within a reverberation chamber is presented. This feature is possible with the use of a time reversal electromagnetic chamber, a concept previously introduced by the present authors 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 movement of either sources or an equipment under test while preserving the high-intensity field levels achieved with reverberation chambers.
