The microwave-drilling technique using an open-end coaxial applicator was disclosed recently. This paper presents new experimental and theoretical results of microwave-drilling studies in various ceramics, including mullite, alumina, and zirconia. The paper reviews the microwave-drill principles and describes the experimental setup and procedures. Aspects of igniting the microwave-drilling process in low-loss materials, and the dynamic impedance-matching adaptation are elaborated. The microwave-drill selectivity feature, found useful for ceramics coatings , is presented. The experimental results are analyzed and explained by a numerical simulation. The advantages and limitations of the microwave-drilling technique for ceramics are discussed.
