Abstract :
Experimental results are been presented to show that when a phase-switched screen (PSS) is configured so that alternate rows of the its active surface are modulated with independent square-wave signals, single side-band (SSB)-type frequency modulation can be imposed onto signals scattered from the PSS surface. By adjusting the phase-offset between the two modulating signals, selective suppression of individual upper and lower sidebands can be achieved
