  In this work, we present near-field image transmission and error vector
magnitude measurement in a rich scattering environment in a metal enclosure. We
check the effect of loading metal enclosure on the performance of SDR based
near-field communication link. We focus on the key communication receiver
parameters to observe the effect of near-field link in presence of
rich-scattering and in presence of loading with RF absorber cones. The
near-field performance is measured by transmitting wideband OFDM-modulated
packets containing image information. Our finding suggests that the performance
of OFDM based wideband near-field communication improves when the metal
enclosure is loaded with RF absorbers. Near-field EVM improves when the
enclosure is loaded with RF absorber cones. Loading of the metal enclosure has
the effect of increased coherence bandwidth. Frequency selectivity was observed
in an empty enclosure which suggests coherence bandwidth less than the signal
bandwidth.
