Abstract:

Formulation of the problem. The effectiveness of electromagnetic field shapers, built on the basis of powerful microwave generators, in most practical problems directly depends on the energy and power of the generated radiation. The increase in energy and radiation power is accompanied by an increase in the volume and mass of the generator and the power supply from the shaper. Moreover, any carrier has a finite mass-size payload resource, which may not allow placing a field shaper with specified radiation parameters on it. Therefore, there is a need for a preliminary assessment of the possibility of placing these devices on existing carriers. Purpose. Determination of the laws that connect the volume and mass of the electromagnetic field shaper with the radiation parameters of the microwave generator (power, duration, repetition period and number of pulses)

Results. General expressions are obtained for estimating the volume and mass of the electromagnetic field shaper constructed according to the “power supply – microwave generator” scheme in a pulse-periodic mode. Loss of idling during pauses between pulses was taken into account. The condition is determined under which the idle loss does not affect the mass-dimensional parameters of the shaper. Regularities are established that connect the shaper volume and mass with radiation parameters when using an ideal electromotive force generator as well as capacitive and inductive energy storage devices as a power source in the mode of generating a sequence of pulses of the same duration with a constant repetition period. The volume and mass of the shaper constructed according to the «explosive magnetic generator – vircator» scheme in various generation modes were calculated.

Practical significance. The results can be used to justify the requirements for mass and size parameters of the electromagnetic field shapers.
