2. Resonant cavities

The study of dielectric resonators, the electromagnetic fields present and resonance modes is based on that of resonant cavities, filled or not with homogeneous dielectric [E1402] .

Transverse electrical resonance modes (TE) or transverse magnetic resonance modes (TM) can be excited at frequencies f _r satisfying the equations below for each type of cavity, whether parallelepipedic or cylindrical.
