In　this　paper,　we　present　a　sound　field　synthesis　technique　based　on　the　mode-matching　and　inverse-filtering　to　manipulate　micro-particles　within　a　given　region.　The　technique　employs　a　set　of　PZT　transducers　evenly　placed　on　the　perimeter　of　a　50　mm-radius　circle　to　generate　and　manipulate　the　desired　local　ultrasonic　filed.　Adjusting　the　parameters　of　driven　signals　applied　to　the　transducer　array　results　in　the　movement　of　the　synthesized　pressure　field　and　hence　the　micro-particles.　We　have　theoretically　derived　the　method　to　calculate　the　ultrasound　transducer　operating　parameters　that　are　required　to　synthesize　the　desired　local　ultrasonic　filed　in　a　chamber　filled　with　deionized　water.　Micro-particles　with　10　mu　m-diameter　are　adopted　as　the　manipulating　targets　and　several　experiments　have　been　developed　to　validate　the　synthesizing　method.　The　method　introduced　here　may　become　a　promising　tool　for　various　applications　in　the　field　of　biological,　material,　and　microelectronics.
