Abstract

THIS PROPOSAL OUTLINES A TWO-YEAR SBIR PHASE II PROGRAM TO FABRICATE AND TEST A SET OF NEGATIVE IMPEDANCE CONVERTERS (NIC) TO WORK WITH AN ARRAY OF FLEXTENSIONAL TRANSDUCERS SPECIFIED IN THE PHASE I STUDY. THE PRIMARY OBJECTIVE IS TO DEMONSTRATE THE ABILITY OF THE NIC TO EXPAND THE TRANSDUCER OPERATIONAL BANDWIDTH TO 2 OCTAVES AT FULL INPUT POWER AND HIGH EFFICIENCY. THE AMPLIFIER WILL HAVE THE CAPACITY TO DELIVER 1000 WATTS PULSE AVERAGE, AT A 15% DUTY CYCLE. THE NIC WORKING WITH THIS SYSTEM WILL DELIVER 100 KVA, PULSE AVERAGE, ALSO AT A 15% DUTY CYCLE.
