Abstract:

The ability of microwave energy to penetrate some kinds of ceramic materials at frequencies of 100 GHz and above suggests that microwave techniques may be useful for the nondestructive evaluation NDE of such materials. The work described in this report demonstrates the basic feasibility of using these techniques to detect and locate various types of inclusions including voids in Si3N4. Inclusions as small as 0.005 inch in diameter have been detected using frequencies in the range 50 to 100 GHz. Author
