Antenna and radio frequency explosive magnetic compression generator are coaxially placed, and the electromagnetic pulse that radio frequency explosive magnetic compression generator produces is input in antenna by coupling coil, and goes out by aerial radiation.
The efficiency of radio frequency explosive magnetic compression generator is to be determined by the energy of aerial radiation.Radio frequency explosive magnetic compression generator is input to energy in antenna and requires antenna all to mate in whole working band with oscillating circuit.Because the resistance (being generally 50 Ω) of antenna exceedes approximately order of magnitude of internal resistance of radio frequency explosive magnetic compression generator, so must consider to adopt impedance transformation to realize the coupling of the two.Because ideal transformer has the effect of impedance transformation, be antenna feed so the present invention adopts the mode of inductance coupling high.The equivalent electric circuit of the radio frequency explosive magnetic compression generator of employing inductance coupling high feed as shown in Figure 7.Wherein, R (t) is the dynamic electric resistor of radio frequency explosive magnetic compression generator, and L (t) is dynamic inductance (being the inductance of stator coil 11), C electric capacity.L
