The results of a three-dimensional analysis of wake field excitation in a slab-symmetric dielectric-loaded resonator
by rigid electron bunches are presented. The complete set of solutions, including the solenoidal and potential parts of
the electromagnetic field, consists of LSM and LSE modes. Each of the LSM and LSE modes contains odd and even
waves. A numerical analysis of wake field excitation by symmetric electron bunches is carried out. The threedimensional
spatial structure of the longitudinal electric field is investigated. The influence of the drift vacuum channel
on the wake field amplitude and on the coherent summation of wakefields for a regular sequence of bunches is studied.
