✦ Synopsis

The sensitic1ity of car ity Q-factor measurements in the cauity perturbation method can be improL5ed by using the differential averaging technique. The complex pemiitthity of low-loss dielectric samples are accurately obtained by eualuating the differential aueragng L'ahes among the original and perturbed frequency responses.

## Abstract The design of a rectangular cavity resonator implies to solve the Maxwell equations inside that cavity, respecting the boundary conditions. The resonance frequencies appear as conditions in the solutions of those equations. When a small piece of a magnetic material is introduced in the
