    "abstract": "Open single-mode metallic cavities operating in nonradiative configurations\nare proposed and demonstrated. Starting from well-known dielectric resonators,\npossible nonradiative cavities have been established; their behavior on the\nfundamental TE011 mode has been predicted on the basis of general\nconsiderations. As a result, very efficient confinement properties are expected\nfor a wide variety of open structures having rotational invariance. Test\ncavities realized having in mind practical millimeter wave constraints have\nbeen characterized at microwave frequencies. The field distribution of some\nrelevant configurations has been modeled by means of a finite-element numerical\nmethod. The obtained results confirm the expected high performances on widely\nopen configurations. A possible excitation of the proposed resonators\nexploiting their nonradiative character is discussed, and the resulting overall\nease of realization enlightened in view of millimeter wave employments.",
