  • Abstract
    A new matching layer design concept has been proposed for narrow band continuous wave (CW) devices. The structure is different from well-known wideband design, A high power transducer structure was designed and fabricated with PVDF-TrFE to operate at 1.4 MHz. A maximum power output of 6-9 W/cm2 with conversion efficiency of 30-35% was observed
