Specific embodiment
Embodiment 1
A method of switched energy storage Microwave pulse device energy extraction efficiency being improved, as shown in figure 3, output electricity
Sense diaphragm 6 is placed between waveguide H-T2 and output waveguide 5 by method of clamping, outputting inductance diaphragm and the main wall of waveguide H-T
Distance L.The placement location of outputting inductance diaphragm 6 is determined by waveguide dimensions, microwave frequency, energy-storing chamber electromagnetic field mode, with waveguide
The distance of the main wall of H-T will change the equivalent impedance of outputting inductance diaphragm according to transmission line impedance equation, so that it is deployed energy and mentions
Structure is taken, its energy extraction efficiency is improved.
Outputting inductance diaphragm is as shown in Fig. 2, parameter is diaphragm spacing d and diaphragm thickness h.Due in energy-storing chamber electromagnetic field mode
The direction of an electric field size of formula does not change, so power capacity is higher.This device can be equivalent to the shunt susceptance in transmission line, defeated
Inductance diaphragm is thicker out, and spacing is smaller, and equivalent susceptance is bigger.
After placing outputting inductance diaphragm, Energy extraction structure can be under microwave energy-storage chamber electromagnetic field mode and working frequency point
Realize impedance matching, energy extraction efficiency can reach 99.99%, as shown in Figure 4.D is by Energy extraction for outputting inductance diaphragm spacing
Structural impedance mismatch, i.e., depending on standing-wave ratio, the ideally impedance mismatching degree Ying Yuneng of outputting inductance diaphragm itself
It is identical that amount extracts structure.For the ease of processing and adjusting, it is proposed that fixed outputting inductance diaphragm thickness, then in such cases, energy
Extraction structural impedance mismatch is bigger, and outputting inductance diaphragm spacing is smaller；On the contrary, Energy extraction structure impedance mismatching is smaller, output
Inductance diaphragm spacing is bigger.The inductance diaphragm of broadside size can also be greater than using spacing as needed, embodiment is similar, different
Place is: Energy extraction structure impedance mismatching is bigger, and outputting inductance diaphragm spacing is bigger；Energy extraction structure impedance mismatching is got over
Small, outputting inductance diaphragm spacing is smaller.
Outputting inductance diaphragm draws energy-storing chamber electromagnetic field mode by Energy extraction structure with the main wall distance L of waveguide H-T
The phase change risen determines.Outputting inductance diaphragm coordination effect with half guide wavelength can be week at a distance from waveguide H-T
