A new technique is described for measuring microwave dielectric constants which overcomes several disadvantages of currently standard methods. Perturbation techniques are used with thin rod samples placed in a TM012 cylindrical cavity in such a manner that all undesirable effects of the ends of the rod are eliminated. A considerable increase in repeatability and ease of measurement is obtained.
