摘要：
The present invention discloses a system and a method for making micro-holes/cavity in workpiece/ objects ranging from soft polymer based materials like PMMA (polymethylmethacrylate) to hard materials like glasses and ceramics using microwave generated plasma as a source of energy. The microwave drilling arrangement of the present invention comprises an enclosed microwave cavity with an electromagnetic source to provide microwave in said cavity and at least one metallic concentrator drilling tool with a pointed drill end for creating concentrated electromagnetic field upon exposure to microwave irradiation which generate plasma for localized melting of a workpiece material and thereby material ablation on the workpiece to thus drill hole in the workpiece.
