Benjamin E. Henty and Daniel D. Stancil. Multipath-Enabled Super-Resolution for rf and Microwave Communication using Phase-Conjugate Arrays. Physical Review Letters, 93(24):243904, December 2004.
We demonstrate experimentally that phase-conjugate techniques can be used to achieve super-resolution focusing of electromagnetic waves in a multipath indoor environment at 2.45 GHz. The focusing phenomena was used to direct independent signals to two locations separated by approximately one-half wavelength, thereby creating two simultaneous channels at the same frequency. An increase in channel capacity is shown to be achievable by an experimental transmission of a 1 Mbps signal over two channels created using a four element phase-conjugate array.
