Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the high-voltage source is arranged externally next to the microwave generator, then the dielectric strength is optimized, but the space requirement increases significantly
Solution Approach 1:
The high-voltage source is nested inside the hollow interior space of the central electrode, allowing the microwave generator to achieve a compact design while maintaining optimized dielectric strength through proper spatial arrangement of internal components
2Volume of stationary object
If the high-voltage source is integrated inside the microwave generator, then the space requirement is reduced for ultra-compact design, but the dielectric strength may be compromised
Solution Approach 1:
The high-voltage source components are nested within the hollow central electrode structure, achieving compact integration while maintaining dielectric strength through proper insulation design and spatial arrangement
Solution Approach 2:
The interior space is filled with dielectric material (gas or liquid) to locally enhance the dielectric strength in critical areas where high electric fields occur, ensuring reliability despite the integrated compact design

This ultra-compact design allows for the microwave generator to be used in vehicles and indoor settings, such as targeted vehicle stopping and disrupting electronic systems, while maintaining dielectric strength through the use of a sealed insulating housing and dielectric fill.
Implementation Method 1
The high-voltage source is preferably formed by a Marx generator... As a result of the short-circuiting of the high-voltage source via the spark gap, strongly oscillating discharge or short-circuit currents with a steep flank are produced
Implementation Method 2
which are transmitted via an antenna-forming radiation element of the microwave generator as microwave energy with a broadband frequency mixture
Implementation Method 3
The interior space of the microwave generator, which is defined and sealed by the two electrodes and the electrically insulating housing sleeve, can be filled with a gaseous or a liquid dielectric to increase the electric strength

AI summary
A microwave generator (10) is described, comprising a hollow central electrode (12) with a hollow radiating element (18) on its front side, and an outer electrode (14) coaxially surrounding the central electrode (12) along an axially extending resonator section (16). The two electrodes (12 and 14) define a spark gap (36) and are connected to a high-voltage source (38). According to the invention, an ultra-compact microwave generator (10) is achieved by arranging the high-voltage source (38) not outside but inside the hollow central electrode (12) of the microwave generator (10).
