High Intensity Electromagnetic Field Generation using a Transportable Reverberation Chamber

نویسنده

  • Frank Leferink
چکیده

A reverberation chamber can create very high field strength with moderate input power. Existing chambers are making use of a paddle wheel to change the resonant modes in the chamber. A transportable reverberation chamber with vibrating walls will be presented. Inside this Vibrating Intrinsic Reverberation Chamber (VIRC) a diffuse, statistically uniform electromagnetic field is created, without the use of a mechanical, rotating, mode stirrer. This chamber results in a better homogeneity and increased field strength compared to conventional mode stirred reverberation chambers. This test setup is very suitable for cost effective intentional electromagnetic interference (IEMI) tests.

Feature Analysis of Electromagnetic Interference Measurement Facilities

This paper presents a feature analysis of two electromagnetic interference test facilities. The one is an anechoic chamber and the other is a reverberation chamber. And then, this paper reviews problems of the current reverberation chamber, the stirrer. In general, a reverberation chamber uses a stirrer to generate a uniform electric field inside it. However, the stirrer is a big sized unit and...

Design and Construction of a Small Reverberation Chamber

This paper describes the design of a small reverberation chamber. The lower usable frequency of the reverberation chamber designed in this paper is 2.3 GHz. The upper usable frequency depends on the conductivity of the walls and it is at least 18 GHz. The introduction gives basic information and usage of the reverberation chamber, while the theory is explained in the next section. Unlike other ...

Optimization of Stirrer with Various Param- Eters in Reverberation Chamber

Reverberation chambers are widely used in electromagnetic compatibility test facilities because they provide a large working volume and are cheaper than other types of test facilities. In addition, they provide a statistically uniform field and generate a high maximum electric field within a relatively large volume. The volume of the cavity, the structure of the stirrer, and high tested frequen...

Reverberation Chamber Low Frequency Field Uniformity Improvement with Conducting Pyramidal Structures

Reverberation chambers are commonly used in industry for measuring electromagnetic interference because they are cost-effective. We attempt to stir modes more evenly inside reverberation chambers by introducing passive field uniformity enhancement (PFUE) structures. These structures augment the existing rotating stirrers. Measured results for a 2.445 Х 2.475 Х 3.72 m reverberation chamber are p...
