## Abstract The design of a cavity resonator implies to solve the Maxwell equations inside that cavity, respecting the boundary conditions. As a consequence, the resonance frequencies appear as conditions in the solutions of the differential equation involved. The measurement of the complex permitt
We present a new and highly stable cylindrical microwave cavity resonator designed for the measurement of the relative permittivities of gases. The cylinder has an internal volume of just 5.7 cm 3 , which makes it the smallest such a resonator reported to date. The equipment and procedure used to me
