Multipath-Enabled Super-Resolution for rf and Microwave Communication using Phase-Conjugate Arrays
2004
Physical Review Letters
Preserved Fulltext
We demonstrate experimentally that phase-conjugate techniques can be used to achieve superresolution 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
