RÉSUMÉ

The possibility of rigorous simulation of the compression of electromagnetic pulses excited by a filament with a current in a plane-parallel waveguide cavity is investigated. The technique of determining the modulation law of the pulses to be compressed, that has been developed in our previous papers, here is generalized to the case where the pulse source is an extraneous current. The process of compression is modeled with this technique for two symmetrical wave packets propagating towards each other in a ring-shaped waveguide. The interference of these packets is demonstrated in the performed numerical experiment. The result of the interference is doubling of the electric field intensity (regarding to the intensity in each separate wave packet) at the point of the waveguide which is diametrically opposed to that one where the external current is located. The obtained results could be used for the design of passive microwave power compressors and in the accelerator engineering.
