A novel time-reversal subwavelength transmission technique, based on pulse-shaping circuits (PSCs), is proposed. This technique removes the need for complex or electrically large electromagnetic structures by generating channel diversity via pulse shaping instead of angular spectrum transformation. It is shown that, compared to our previous time-reversal system based on chirped delay lines, the PSC...
This letter proposes a novel approach based on time reversal (TR) technique to achieve multiplexing in a single antenna system by using pulse shaping network (PSN). The PSN used in this letter is easy to design and can conveniently control the focusing performance of the TR technique. Experimental results show a good performance of the new scheme.
