In the present paper the excitation of cylindrical structures (waveguide and resonator) by helix and axial electric currents have been considered using exact electromagnetic approach. In the solution of the problem the coupling of resonator with input and output coaxial lines and possible excitation by elecon beam and by input signal are considered. Beam current is supposed to be given and problem is linear and time-independent. The results can be used for processes simulation in the systems with helical slow-wave structures, such as TWT. This approach can be applied also for investigation of wave propagation in photonic crystals with small helical inclusions. Using such artificial environment allows to well simulate environment with large permittivity.
