1. A method for drilling a hole in a non-conductive solid body, the method comprising:
- (a) generating microwave radiation; and
(b) concentrating the microwave radiation onto a small region of the solid body so as to generate heat sufficient to remove a volume of the solid body, thereby forming a hole in the solid body.

Abstract
A microwave device and corresponding method for cutting, and especially drilling into, a solid body of non-conductive material employ a microwave source which provides microwave radiation, typically through a waveguide, to a concentrator. The concentrator is configured to concentrate the microwave radiation onto a small region of solid body, thereby generating sufficient heat in that region to liquefy a volume of the material to form a hole. The device and method may be used to perform various drilling, cutting, nailing, joining and welding operations on a wide range of dielectric materials including ceramics, concrete and stone.

20. A microwave device for cutting non-conductive materials, the device comprising:
-
(a) a microwave source of microwave radiation; and (b) concentrator means coupled to said microwave source so as to receive the microwave radiation, said concentrator means being configured to concentrate the microwave radiation onto a small region of the non-conductive material, wherein said concentrator means is formed with at least one inner conductor and an outer conductive sheath surrounding said inner conductor, and wherein said outer conductive sheath terminates at an open end and said inner conductor extends beyond said open end. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
