THE METHOD OF DETERMINING AT MICROWAVE FREQUENCIES THE DIELECTRIC CONSTANT OF A CRYSTAL SUCH AS A DIAMOND COMPRISING FORMING A FIRST SERIES OF RODS, EACH HAVING A PRESELECTED DIELECTRIC CONSTANT, MEASURING THE INDIVIDUAL FREQUENCY SHIFT RESULTING FROM THE INSERTION OF EACH OF SAID RODS IN A MICROWAVE RESONANT CAVITY, EMBEDDING SAID CRYSTAL SUCCESSIVELY IN A SECOND SERIES OF RODS IDENTICAL IN DIELECTRIC CONSTANT TO SAID SERIES OF RODS, AND MEANS URING THE FREQUENCY SHIFT IN SAID MICROWAVE RESONANT CAVITY RESULTING FROM THE SUCCESSIVE INSERTION OF EACH OF SAID SECOND SERIES OF RODS INCLUDING SAID CRYSTAL INTO SAID MICROWAVE RESONANT CAVITY.
